摘要
建立一种微波消解-氯离子选择电极法测定废弃油脂中氯离子含量的新方法。通过对不同样品前处理方法进行比较,研究微波消解不同升温程序对测定结果的影响,经过加标回收和重复性试验,最终得出该方法操作简单,分析速度快,值得推广。
A new method of determining chlorine ion in waste oil by chlorine ion selective electrode was reported in this paper. The pretreatment methods of different samples, the influence of microwave digestion and different heating procedures on the measurement results were studied. The method has advantages of easy operation, rapid analysis and is worth spreading.
