Hydrolysis activities of PACC (particle of agarose-Ce4+ complex, newly made through double emulsification) forcompounds containing phosphodiester or peptide bonds were studied. The results showed that PACC could hydrolyzeorganophosphorous pesticides not only in water but also in vegetable juice or tea extract. Hydrolysis rates of methamidophos,omethoate and chlorpyrifos in water are 32.39%, 27.12% and 46.62% respectively, those of chlorpyrifos and methami-dophos in mung sprout juice 38.28% and 35.45% respectively, and that of chlorpyrifos in tea extract 59.76%. Hydrolysisrates of BSA (bovine serum albumin) in water and protein in tea extract by PACC increase by 54.30% and 86.46% respec-tively as compared with the control.
