湿法预处理-电感耦合等离子体原子发射光谱法测定低冰镍的金、银、铂、钯含量
Determination of Gold,Silver,Platinum,and Palladium Content in Low-Nickel Matte by Wet Pretreatment-Inductively Coupled Plasma Atomic Emission Spectroscopy
摘要
Abstract
In this experiment,nitric acid and sulfuric acid are used for pretreatment to remove elements such as copper and nickel from low-nickel matte,then the precious metals in low-nickel matte are enriched and impurities are removed by using the fire assay method,subsequently,the contents of gold,silver,platinum,and palladium are determined by using inductively coupled plasma atomic emission spectroscopy(ICP-AES).The experimental results show that this method can achieve a lower detection limit and a wider detection range,and copper has been removed in the pretreatment,reducing the use of lead oxide and achieving the detection of multiple elements,meeting the detection requirements for large sample sizes.关键词
