摘　　要：对2%绿清灵可溶粉剂的有效成分十八烷基三甲基氯化铵在橘园土壤中的残留进行连续采样分析,测定其动态残留量并分析其消解状况。通过间接光度色谱法进行分析测定,结果表明:十八烷基三甲基氯化铵在橘园土壤中消解较快,消解半衰期为3.08～4.49d,消解速率符合一级动力学方程。In this study,through continuous sampling,analysis and determination of the active ingredient of a new type citrus caricide-2% Green Qing Ling,residues digestion of octadecyl trimethyl ammonium chloride in citrus orchard soil have been analyzed. By indirect photometric chromatography analysis of OTAC,the results showed that OTAC faster digestion in citrus orchard soil,digestion half-life of 3.08-4.49 d,digestion rate consistent with a kinetic equation.
