Growth Inhibition and Mechanism of Cetyltrimethyl Ammonium Chloride on Chlorella vulgaris
|
Abstract:
Growth inhibition of cetyltrimethyl ammonium chloride(CTAC),a cationic surfactants,on Chlorella vulgaris was investigated at batch culture in laboratory.Furthermore,the corresponding mechanisms were studied by the determination of absorption capacity,Zeta potential,activity of acid phosphatase and ultrastructure of algae.Results show that the growth inhibition by CATC is enhanced with its concentration increasing from 0.1(mg/L) to 1(mg/L),and 96 h-EC_(50) of CTAC is 0.18(mg/L).In the presence of 0.3(mg/L) C...
