Through the re-search, the proper AchE concentration for hydrolysis of 1 ml 1mmol/L substrate and I50 val-ues of the agrochemicals to AchE are decided. It is proved that Asch-DTNB method is a rapid test tool for agrochemical residues in fruits and vegetables.A rapid test card has been developed with sensitivity of 0.05mg/L.展开更多
文摘Extraction of AchE, relationship between substrate and enzyme concentration, and inhibition effects of the agrochemicals to AchE are discussed in this paper. Through the re-search, the proper AchE concentration for hydrolysis of 1 ml 1mmol/L substrate and I50 val-ues of the agrochemicals to AchE are decided. It is proved that Asch-DTNB method is a rapid test tool for agrochemical residues in fruits and vegetables.A rapid test card has been developed with sensitivity of 0.05mg/L.
