Abstract

A new method has been developed for the determination of trace metal As in health-giving drink by AA-670 atomic absorption spectrophotometry attached VA-90 atomization. The method is convenient to determine element in water. The results show that the method has good precision and accuracy. The detection limit is 2 ng.L-1 for As. The relative standard deviation is 5.4%-6.1%, and the rates of recovery is 87.5%-115%. This method has been applied to the determination of health-giving drink with satisfactory results.

摘要

采用配有VA - 90原子化器的AA - 670原子吸收分光光度法，开发了一种测定保健饮品中痕量金属砷的新方法。该方法便于测定水中的元素。结果表明，该方法具有良好的精密度和准确度。砷的检出限为2 ng.L-1。相对标准偏差为5.4% - 6.1%，回收率为87.5% - 115%。该方法已应用于保健饮品的测定，结果令人满意。
