The advanced oxidation processes are considered to be suitable for solving some water issues due to their enhanced features in photo-oxidation of organic compounds. Recent nanoparticle-mediated photo-oxidative processes, involving zinc oxide and titanium dioxide semiconductors, constitute a proficient, resourceful, and sustainable method which is developed primarily to remove phenols and aromatic dyes from groundwaters and wastewaters. This review focuses on the evolution of nanoparticle-mediated titanium dioxide and zinc oxide catalysts with a band edge effective in the UV region. This catalytic medium has subsequently been modified to be effective in the visible region. In this regard, a brief discussion on the substitution of metals and nonmetals on Zn2+, Ti4+, or O2- sites for efficient photocatalytic performance under visible light is also emphasized. The emphasized points are: (i) degradation kinetics and (2) operating parameters affecting the catalytic photo-oxidation and (3) concluding remarks drawn from collected surveys. The recent progresses made in the production of doped photocatalysts for the mineralization of phenols and dyes are also highlighted.","PeriodicalId":21744,"journal":{"name":"Separation & Purification Reviews","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78435797","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The concentration of thorium in the environment may increase due to waste that is produced from human activities like mining, rare-earth extraction, and others. If this waste is not handled properly, thorium may leak and cause water contamination. This review summarises the methods of thorium removal from wastewater. The article addresses the main features of the techniques for thorium removal by physicochemical processes such as chemical precipitation, ion exchange, adsorption, electrochemical and membrane filtration. Their advantages and limitations in the applications are evaluated. Bioadsorption and natural material are widely used in the removal of thorium. However, in the near future, the electrosorption process seems to be the most promising method to treat wastewater since it can overcome limitations of adsorption techniques with the help of electric current to have a more efficient and rapid process. It should be noted that all the techniques able to remove thorium depend on pH, temperature, the concentration of thorium and other wastewater components. In general, the technical applicability, simplicity of technique and cost-effectiveness are the key factors in selecting the most suitable treatment for removal of thorium.","PeriodicalId":21744,"journal":{"name":"Separation & Purification Reviews","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90792323","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although molecular imprinting is an old idea, its potential as molecular recognition tool in analytical chemistry has been revived in recent times. This review intended to comprehensively discuss and evaluate the recent progress in the applications of molecularly imprinted polymers (MIPs) in analytical chemistry. A concise introduction for new readers in the field is followed by the comprehensive critical review of these developments in MIP technology and their applications in analytical chemistry. This review is divided into three sections namely, extraction, sensors and chromatography. The three sections are further separated into several sub-sections. The applications related to compound extraction are subdivided into extraction of toxins and bioactive compound extraction. MIPs as sensors are subdivided into luminescence probes, surface plasmon resonance (SPR) sensors, quartz crystal microbalance (QCM) and electrochemical sensors. Finally, the MIP applications as stationary phase for chromatography are elaborated. This section is subdivided into HPLC and capillary electrochromatography (CEC). The significant aspects of applications of the molecular imprinting polymers in analytical chemistry are evaluated focusing majorly on literature appeared in last five years.","PeriodicalId":21744,"journal":{"name":"Separation & Purification Reviews","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91477833","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Seawater desalination has become essential for the supply of fresh water mainly due to the development of seawater reverse osmosis (SWRO). The depletion of conventional extractable resources and the increase in the use of certain metals encourage the development of nonconventional sources. Attending to the increasing global desalination capacity, the extraction of minor components concentrated in the SWRO brines can become a valuable source of target compounds. This work evaluates the potential interest for extraction of minor components in SWRO concentrates. The target metals are selected attending to the relevance of their applications, the market trend, the depletion of conventional resources and the state of the art of the extraction technologies. The main challenges to be overcome are highlighted. Results are summarized in a ranking where the inputs for research are categorized in three levels resulting in a useful decision tool. Cs, In and Rb are pointed as promising metals to upgrade their extraction technologies from SWRO concentrates. Significant research contributions are needed in order to develop viable strategies for the recovery of valuable materials from SWRO brines.","PeriodicalId":21744,"journal":{"name":"Separation & Purification Reviews","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73979623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their structural diversity, susceptibility to heat, pH, and copigmentation complicate its extraction and purification. The use of high hydrostatic pressure (HHP) assisted extraction has proven to be a good alternative to conventional techniques as it combines elevated pressure (100–800 MPa), moderate temperatures (30–60°C), and short processing times (3–10 min). The HHP process is based on the Pascal and Le Chatelier’s principles which state that pressure is uniformly transmitted and distributed in all directions. HHP allows the enhancement of mass transfer rates by increasing cell permeability and increasing the diffusion of secondary metabolite, which leading to higher extraction yields, fewer impurities on the final extract and the possibility of extractions at room temperature with preservation of thermo-sensitive structures. This review examines the basic principles of the HHP technology, including its mechanisms, analytical procedure and its effects on plant materials as well as a discussion on the most important parameters that affect the performance of this technology, its advantages, and disadvantages. Lastly, the applications of HHP for the recovery of phenolic compounds, with emphasis on anthocyanins, are discussed.","PeriodicalId":21744,"journal":{"name":"Separation & Purification Reviews","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91344015","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
