摘　　要：建立了洗面奶微波消解处理条件的优化方法,通过L9(34)正交试验设计,优化了微波消解洗面奶过程中的3个主要影响因素,得到合适的处理条件为:以5 mL硝酸消解0.5 g洗面奶,消解时间为10 min,消解温度为150℃。结果表明,在此处理条件下,对不同样品检测的回收率为94.12%～104.26%,相对标准偏差为0.68%～2.03%。A method for optimization of microwave digesting treatment of facial cleaning milk was established via L9 （ 34 ） orthogonal experimental design. Three major factors in the process of microwave digesting treatment of facial cleaning milk were optimized. Recommended treatment conditions were identified as：5 mL HNO3 to be used for a sample of O. 5 g facial cleaning milk;lO min of digestion time and 150 ℃ of digestion temperature. Results showed that the recovery achieves between 94. 12% and 104. 26%, and the relative standard deviation achieves between 0.68% and 2.03%.
