Abstract: Attapulgite was purified by means of natural precipitation and modified by cetyltrimethyl ammonium bromide (CTAB), and then the effect of the attapulgite on the growth of Alexandrium tamarense and Prorocentrum donghaiense was investigated. It was shown that some quartz was removed from attapulgite by purification. The bunchy aggregation of attapulgite was separated by CTAB modification and the surface of attapulgite was endowed with organic structure. The CTAB modified attapulgite decreased the content of protein and chlorophyll a of Alexandrium tamarense and Prorocentrum donghaiense remarkably, and the growth of the algea was inhibited.
