摘要
本文研究了ＳｉＯ２为载体的催化剂中铂的直接测定方法。该方法的特征量为２１ｐｇ，检出限为１４μｇ／ｍｌ。对于铂含量为０．００５％的催化剂，相对标准偏差在４．９％～９．５％之间，回收率在９１％～１００％之间。
A method is studied which is used for determination of platinum in catalysts which takes SiO 2 as carrier The characteristic mass is 21μg,the lower limit is 14 μg/ml For catalyst which contains platinum about 0 005%,the relative standard deviation is 4 9～9 5%,the recovery is 91～100%
