摘要
紫外分光光度法在测定污水中油含量时,存在着石油醚脱芳烃技术实用性差、分液漏斗使用的润滑剂引起误差等问题。针对测定前水样的处理,通过简化石油醚的预处理、以容量瓶代替分液漏斗、以滤纸斗代替砂芯漏斗等措施,对紫外分光光度法测定水中油含量的技术进行了改进。
In determining oil content in the sewage by ultraviolet spectrophotmetry, it ＇ s shown that the technique of eliminating aromaticity from petroleum ether is not good in practicability and the lubricant used for tundish is easy to cause errors, etc. From simplifying the pre-treatment of petroleum ether, replacing the funnel by content bottle and taking the filter paper funnel as aseparatory funnel, the technique is improved.
