摘要
对提高水中矿物油测定结果准确度的探讨在紫外分光光度法测定水中矿物油,存在着标准油品、石油醚纯度、石油醚萃取液体积定容等因素影响测定结果的准确度.本文对上述因素进行实验对比,明确影响因素,提出改进建议.
Determining the mineral oil in water by wltraviolet spectrophotometric methods, the degree of pteciseness was influenced by standard oilgrade, purity of ligroin and lacation of the extractant volnme. In this paper above - mentioned factors were experimentally contrasted, clearly made and some suggestions for inprovement of the method pnt for ward.
