Abstract:
Bentonite and humus are very important parts in soil. They can adsorb pesticides intensively because of their complicated structure and many functional groups. Chlorpyrifos and triazophos were quantitatively analyzed by internal standard method using AE. SE-54 capillary column and ntetradecane as the internal standard substance. The adsorption of chlorpyrifos and triazophos on bentonite and humus was studied by using the equilibrium oscillometry. The results showed that standard deviations were between 015 and 061; coefficients of variation were between 098 % and 151 %; the recoveries of chlorpyrifos and triazophos were between 8933 %—124 % and 97 %—116 % respectively; the detect limits were 114×10-11 g/g and 139×10-11 g/g,respectively. Humus had great adsorption capacity than bentonite. The adsorption of chlorpyrifos and triazophos fitted well with the Langmuir equation on bentonite. On the other hand, it fitted well with both Freundlich equation and Langmuir equation on humus.
