摘要
Abstract
To establish a determination method for heavy metal Pb in paper cups .Igniting and ashing the paper cup of a certain quantity ,and dissolving the residue to a certain volume with water ,making the solution with various volume react with thiacetamide and color gradient can be formed ,comparing with which standard Pb ’ reaction ,accordingly to determine the content interval of heavy metals .The method is simple ,accurate and reliable.The limit of quantitation is 2 ppm.It can be used for the determination of heavy metal Pb in paper cups.The result of determination can be showed that heavy metal is excessive in paper cups .关键词
