摘要
提出了用磷钒钼酸分光光度法测定汽油中磷含量的方法，通过对汽油中可能存在的共存离子干扰进行了考察，确定了最佳测试条件。对合成标准样品分析，其相对误差小于±３．０％，相对标准偏差小于２．３％，对实际样品进行分析并进行了加标回收试验，磷回收率达到９８．８％～１０３．９％。是一种快速、可靠测定汽油中磷含量的方法。
Amethod for the determination of phosphorus in gasoline by molybdovanado-phosphoric acid spectrophotometry is proposed. The interference ions probably presented in gasoline are examined, and the optimum determination factors are determined. For the determination of the synthesized samples and gasoline samples the relative error is less than ±3.0%, relative standard deviation is less than 2.30%, and rate of recovery of phosphorous is 98.8%～103.9%. The method is simple and convenient.
