摘 要: 通过对活性炭的改性, 提高活性炭对钯和金的吸附作用. 提出实用而简便的同时测定钯和金的方法. 样品经过王水溶解、活性炭吸附富集、灰化除炭、再溶解等过程, 利用原子吸收法, 直接测定钯和金的含量. 方法准确方便, 适用范围广. The absorption function to palladium and gold by improving active carbon is strongly perfected.A simultaneous determination of palladium and gold is established by atomic absorbing spectroscopy(AAS) with characters of practicality,simple and convenience.Being dissolved by aqua regia, concentrated by active carbon, and re_dissolved after incinerating to remove carbon,the amounts of palladium and gold in the samples can be directly analyzed by AAS.This is an accurate method to determination of palladium and gold simultaneously with widely application area.
