Supercritical fluids can be used as antisolvents to precipitate selectively target compounds from a mixture and to remove impurities by the Supercritical Antisolvent technique (SAS). The present decade has experienced a considerable increase in the number of publications that apply this technique to natural extracts, especially for the isolation of polyphenols and carotenoids from plants and microalgae. However, the lack of a clear terminology and purpose adds confusion to the topic. The proposed review aims at defining a research field that consists in applying SAS to natural extracts for the purification of target compounds. To do so, we trace back the origin of the field, discuss the different terminology used to refer to such processes, and suggest appropriate terms for the process and for reported results. This work explores the scope of the topic by compiling all works published to date from a scattered literature, using all possible process terminologies for the search. The information given aims to highlight the most promising applications explored so far and possibly inspire further research.","PeriodicalId":21744,"journal":{"name":"Separation & Purification Reviews","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87228998","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}

Fluorescent coating, also known as phosphor, converts UV rays to visible light. Various chemical compounds, individually or mixed in certain weight ratio, are used as phosphor. Phosphor prepared from rare earth (RE) compounds is energy-efficient. Various components including phosphor are meant to be recycled from FLs once they cease to operate. Review of literatures related to recycling of phosphor suggested that few papers were published prior to 2009. However, there was avalanche of relevant research articles in the next decade. Although RE phosphors were developed in 70s, their use in FLs gained market only after 2009 when energy protection agency passed a resolution to increase the efficiency of the lamps. In the last decade, researchers have done massive work on recycling of phosphor. In the mean time, they switched from one extractive technique to another to overcome the limitations of the former process. In this review, we have investigated the need of switching from one technique to another. We discovered the gaps in these literatures and proposed what needs to be done to fill these gaps. Flow-sheets prepared by compiling the most efficient techniques have been proposed at the end.","PeriodicalId":21744,"journal":{"name":"Separation & Purification Reviews","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83464808","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}

With an ability to perform continuous and deep deionization process without regenerating chemicals, EDI has found a number of new interesting applications such as in wastewater treatment, separation and purification of biotechnology products, and other potential fields. The growing interest has necessitated the development of EDI stack construction and configuration to achieve a better performance. In addition, several studies have been performed to gain a better understanding of ion transfer mechanism in the EDI system. This paper focuses on the mechanism of ionic separation in EDI including the role of ion-exchange resin (IER) and water dissociation reaction as well as its effects on the deionization process. The main technological parameters determining EDI performance are overviewed. Membrane stack configurations along with their advantages and limitation and their development are also pointed out.","PeriodicalId":21744,"journal":{"name":"Separation & Purification Reviews","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91544616","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}

However, few reviews focused on the state-of-the-art developments in ion imprinting technique. Ions and their analogs have a charge and usually similar physical and chemical properties, but less functional groups than molecules. The slight differences in charges, sizes and shapes of ions determine the structure–activity of metal–ligand complexes and imprinted materials. In this review, we focused on the internal connections between each component at coordination and polymerization stages with the affinity and selectivity of the imprinted materials. Advanced imprinting routes such as multiple-template, dual-template docking oriented ionic imprinting and nanocomposite ion imprinted membranes were elaborated. Computational simulation was highlighted for the prediction of functional monomers, binding mechanisms and selectivity. Multiple antifouling enhanced strategies for ion imprinted membranes were put forward to alleviate the trade-off relationship between treated volume and time. The review should provide researchers with new perspectives to explore ion imprinting technology and stimulate more creative breakthroughs in ion separation and purification fields.","PeriodicalId":21744,"journal":{"name":"Separation & Purification Reviews","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85305933","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}
