摘要
探讨了紫外分光光度法测定调味品中苯甲酸含量 ,通过正交实验确定水浴温度 10 0℃、馏液体积 5 0mL、水浴时间 10min为最佳提取氧化条件。该方法检测成本低廉 ,测定程序方便快捷 ,不需大型仪器和特殊试剂 ,可应用于一般工厂实践中。
This paper has reported UV spectrophotometric to determine benzoic acid in condiment. By crossexperiment, the optimum conditions(water bath temperature 100℃,distillate volume 50mL,water bath time 10min)are determined. With low costs and convenient procedure, this method can be applied in common factories without any large equipment and special reagent.
