摘　　要：浆层纸行业标准QB/T 2 30 3-97中铁和铜的测定 ,样品预处理采用灰化法 ,过程很繁琐 ,费时费工。介绍了用硝酸及高氯酸处理试样后进行铁、铜含量的测定分析 ,方法简便 ,回收率高 ,分析结果令人满意。According to QB/T 2303-97,the sample was pretreated by cineration when the iron and copper content in coated paper was detected. The process was complex and time wasting. Another pretreating method was that the sample was dissolved in nitric acid and perchloric acid. It proved that the method was simple and convenient with accurate results.
