There is a large amount of studies surrounding the usage of agro-industrial waste (AIW) for the adsorptions of organic pollutants (dyes) and inorganic pollutants (heavy metals) in water/wastewater. This method is normally treated as an alternative approach to the conventional water/wastewater treatment. However, there are some increasing interests for investigators to identify novel adsorption materials for pollutants removal. It is particularly noteworthy that most AIW wastes are not currently used at the original state, but modified in a variety of ways to reinforce the porosity and adsorption surface area of the material. Nanostructuring, activation, carbonization, and grafting are some common modification technologies of agricultural waste adsorbents. Besides, the characteristic, preparation and application of adsorbents from various industrial wastes, including natural materials and biosorbents, were summarized. Additionally, the challenges and perspectives for future researches of waste-derived adsorbents were studied. This review provides an important insight on using AIWs as precursor materials for preparing adsorbents in water/wastewater treatment.
有大量研究围绕着农业工业废物（AIW）在水中/废水中吸附有机污染物（染料）和无机污染物（重金属）的用途展开。这种方法通常被视为传统水/废水处理的替代方法。然而，研究人员越来越有兴趣寻找新型吸附材料来去除污染物。值得特别注意的是，大多数 AIW 废物目前并未以原始状态使用，而是经过各种方式进行了改性，以增强材料的孔隙率和吸附表面积。纳米结构化、活化、碳化和接枝是农业废物吸附剂的一些常见改性技术。此外，还总结了包括天然材料和生物吸附剂在内的各种工业废物（包括天然材料和生物吸附剂）衍生吸附剂的特性、制备和应用。此外，还研究了未来利用废物衍生吸附剂进行研究的挑战和前景。本文综述了将 AIW 作为制备水/废水中吸附剂的前体材料的重要见解。
