摘要
根据HJ970-2018水质石油类的测定紫外分光光度法(试行)及《四川省市场监督管理局关于简化办理HJ673-2018、HJ970-2018标准扩项流程公告》要求,以正己烷为萃取剂,采用紫外分光光度法对新方法进行技术确认,通过对技术指标逐一分析,表明质控结果符合要求。该方法操作简便,效果较好,能满足实验室申请资质认定及扩项的要求。
According to requirements to"HJ970-2018 Water Quality-Determination of Petroleum-Ultraviolet Spectrophot ometric Method(Trial)"and the"Announcement of Simplifying the Processing of Extension Items of HJ673-2018 and HJ970-2018 Standards by Sichuan Provincial Market Supervision Administration",the new method was confirmed by ultraviolet spectrophotometric method by taking n-hexane as extractant.By analyzing the technical indexes one by one,it has shown that the quality control results meet the requirements.This method is simple and effective,and can meet the requirements of laboratory qualification recognition and extension.
