摘　　要：[Objective] The research aimed to investigate the influences of each factor in the combination of Ca（ClO）2 and O3 on removing carbendazim residues from kumquat. [Method] By using Box-Behnken response surface methodology （RSM）, the effects of initial concentration of carbendazim, soaked time of Ca（ClO）2 solution, soaked time of ozone water and Ca（ClO）2 concentration on removing carbendazim residues from kumquat were studied. [Result] In the test range, the effects of each factor on removing carbendazim residues from kumquat were soaked time of ozone water, soaked time of Ca（ClO）2 solution, initial residual amount of carbendazim and concentration of Ca（ClO）2 solution in turn. By fitting the experimental result, the quadratic polynomial model of relationship between residual amount of carbendazim and the above each factor was obtained. The verified experimental result showed that the model had high precision. [Conclusion] The model could be used to guide using the appropriate soaked time of Ca（ClO）2 solution, soaked time of ozone water and Ca（ClO）2 concentration under the certain initial concentration and residue limits of carbendazim, which guaranteed obtaining the expected residue limits of carbendazim.[目的]探讨次氯酸钙和臭氧组合的诸因素对去除金橘多菌灵残留的影响。[方法]采用Box-Behnken响应面设计方法(response surface methodology,RSM)开展了多菌灵初始浓度、次氯酸钙水溶液浸泡时间、臭氧水浸泡时间、次氯酸钙浓度等因素对去除金橘多菌灵残留作用的研究。[结果]在试验选取的区间内,各因素对去除金橘多菌灵残留作用由大到小依次为臭氧水溶液浸泡时间、次氯酸钙水溶液浸泡时间、多菌灵初始残留量和次氯酸钙溶液浓度。对试验结果进行拟合得到了金橘多菌灵残留量与上述各因素关系的二次多项式模型,验证试验结果表明模型具有较高的精确度。[结论]该模型可以用于指导在确定多菌灵初始浓度和残留限值条件下,采取恰当的次氯酸钙溶液浸泡时间、臭氧水浸泡时间、次氯酸钙浓度等综合处理措施,以保证获得期望的多菌灵残留限值。
