To prevent the future shortage of fresh water and to keep up with the current demand for water, wastewater reuse, and recycling are among the most pressing issues that must be addressed immediately. So far, many technologies have been used to remove both inorganic and organic pollutants from wastewater. Unfortunately, modern water treatment technologies are still out of reach financially for many developing nations, making it difficult for them to eliminate these toxins. Moreover, increasing environmental toxicity from solid waste exposures is also a major cause of worry. Intending to combat these issues, research efforts have increased to develop an efficient, eco-friendly and low cost biosorbent from agricultural waste to treat wastewater. As a result, there has been an increased focus on identifying locally and regionally accessible agriculture wastes for the removal of heavy metals/metalloids and dyes. This article aims to review a multidisciplinary approach to handle agriculture waste as a potential resource for wastewater treatment. A comprehensive discussion is included on the fundamentals of the biosorption and the involved mechanism. The strategies to improve the efficiency of biosorbents are discussed. In addition, current developments in various biosorbents derived from different agricultural waste and their application to remove toxic elements using diverse methods have been reviewed to set the stage for further investigation. Finally, regeneration of biosorbents and current challenges to implement biosorbents are addressed. This article will help to bridge the gap between laboratory findings and industrial application, leading to the development of more efficient systems for removing pollutants.</p></div>","PeriodicalId":34303,"journal":{"name":"Applied Surface Science Advances","volume":null,"pages":null},"PeriodicalIF":6.2,"publicationDate":"2023-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666523923001964/pdfft?md5=30954c3f54fcb8ca81dadd8f3484228f&pid=1-s2.0-S2666523923001964-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138839035","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we developed an easy method for preparing sucrose-derived activated carbon (SAC) with desirable hierarchically porous structures by combining the foaming of molten sucrose, dual-templating (K<sub>2</sub>C<sub>2</sub>O<sub>4</sub>·H<sub>2</sub>O and CaCO<sub>3</sub>), and sequential etching by dual-templating activators at elevated temperatures. As an adsorbent, SAC–800 has a high specific surface (1594 m<sup>2</sup>/g), with rich both micro- and mesopores (microsurface vs external surface area is 812 and 782 m<sup>2</sup>/g). As a result of its desirable hierarchically porous structures, it adsorbs dyes fast and efficiently, attributed to the rich specific surface area that favors adsorption capability and pore size distribution that affects mass transport and adsorption speed. The adsorption for Rhodamine B and Congo Red is spontaneous and endothermic process. The adsorption capacities reach 357 and 780 mg/g for Rhodamine B and Congo Red, respectively, while the rate constants for adsorption (k<sub>a</sub>) and desorption (k<sub>d</sub>) for Rhodamine B are 4.23 × 10<sup>–3</sup> L/(mg·min) and 0.12 L/min, and 1.02 × 10<sup>–3</sup> L/(mg·min) and 5.6 × 10<sup>–3</sup> L/min for Congo Red. With the easy preparation procedure and the desirable hierarchically porous structures, sucrose-derived activated carbons are promising candidates for potential practical applications.</p></div>","PeriodicalId":34303,"journal":{"name":"Applied Surface Science Advances","volume":null,"pages":null},"PeriodicalIF":6.2,"publicationDate":"2023-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666523923001903/pdfft?md5=989430b3b52122928e6aea9d074b9c2f&pid=1-s2.0-S2666523923001903-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138582293","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
