Abstract :
Attapulgite was purified by natural precipitation and modified by cetyltrimethyl ammonium bromide (CTAB), and the effect of the modified attapulgite on the growth of Alexandriumt amarense and Prorocentrum donghaiense was investigated. It was shown that some quartz was removed from attapulgite by purification. The bunchy aggregation of attapulgite was dispersed 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 Alexandriumtam arense and Prorocentrum donghaiense remarkably, and the growth of the algae was inhibited.
