Red mud (an aluminium industry waste) has received wide attention as an effective adsorbent for water pollution control, showing significant adsorption potential for the removal of various aquatic pollutants. In this review, an extensive list of red-mud-based adsorbents has been compiled and their adsorption capacities (maximum uptake value of the adsorbent for the pollutant or adsorbate being removed) for various aquatic pollutants (metal ions, dyes, phenolic compounds, inorganic anions) are presented. The review provides a summary of recent information obtained using batch studies and deals with the adsorption mechanisms involved. It is evident from the literature survey that red mud has been found to be efficient for the removal of various aquatic pollutants, especially arsenic and phosphate. However, there is still a need to investigate the practical utility of these adsorbents on a commercial scale.
赤泥（一种铝工业废物）作为一种有效的水污染控制吸附剂，受到了广泛关注，对各种水污染物具有显著的吸附潜力。在这篇综述中，我们汇集了大量基于赤泥的吸附剂，并介绍了它们对各种水污染物（金属离子、染料、酚类化合物、无机阴离子）的吸附容量（吸附剂对被去除的污染物的最大吸收值）。该综述总结了使用批量研究获得的最新信息，并讨论了所涉及的吸附机制。从文献调查中可以明显看出，赤泥已被证明对去除各种水污染物，特别是砷和磷酸盐，具有很高的效率。然而，仍需要研究这些吸附剂在商业规模上的实际应用。
