Abstract

The increasing anthropogenic pressure results in environmental pollution and thus adversely affects the integrity of ecosystems. Consequently, various methods of removing pollutants from effluents have been developed and used to minimise this negative impact, with adsorption on clay minerals identified as the most promising approach. This review examines the adsorption of heavy metals, radionuclides, and organic pollutants on clays/clay minerals and their composites under diverse conditions and deals with the applications of these materials in the construction of engineering barriers for waste management. Additionally, we discuss the efficiency and mechanisms of pollutant adsorption on clays subjected to various treatments and modifications while describing the beneficial effects of such modification/treatment on adsorption performance, reusability, and in vivo/in vitro toxicity.

污染物的吸附行为:重金属、放射性核素、有机污染物在粘土及其矿物质(原料、改性和处理)上的吸附行为:综述

人为压力的增加导致环境污染，从而对生态系统的完整性产生不利影响。因此，人们开发了各种从污水中去除污染物的方法，并将其用于最大限度地减少这种负面影响，其中粘土矿物吸附被认为是最有前途的方法。本文综述了粘土/粘土矿物及其复合材料在不同条件下对重金属、放射性核素和有机污染物的吸附，以及这些材料在建设工程废物管理屏障中的应用。此外，我们讨论了经过各种处理和改性的粘土对污染物吸附的效率和机制，同时描述了这种改性/处理对吸附性能、可重用性和体内/体外毒性的有益影响。
