摘　　要：海泡石资源丰富,廉价易得,被广泛用于各类废水的处理。详细综述了海泡石的改性方法、改性条件及其特点,介绍了海泡石及改性海泡石在含铬废水处理中的应用,总结海泡石吸附剂的再生方法。指出海泡石及改性海泡石在含铬废水处理方面需要对吸附去除机理和吸附剂的再生方面深入研究。As a cheap, rich resource and available clay minerals, sepiolite was widely used in various types of wastewater treatment. In this paper, characteristics of sepiolite, methods and conditions of sepiolite modification were reviewed in detail, application of sepiolite and modified sepiolite in chromium-contai- ning wastewater treatment and regeneration methods of the adsorbent were summarized. It was pointed out that adsorption mechanism and adsorbent regeneration need to be further studied in this field.
