摘要
以无水亚硫酸钠作为抑制剂 ,用硫酸溶液浸出矿样 ,浸出液用原子吸收法测定铜 ,准确测定矿样中低含量的氧化铜矿物。无水亚硫酸钠浓度 1% ,硫酸浓度 3 % ,浸出时间 45min ,测定结果的标准偏差为 0 0 0 2～ 0 0 0 4,相对标准偏差 4 3 %～4 5 %。
Copper ore samples contained a few of oxide copper minerals is leached in solution of 3% H 2SO 4 and 1% Na 2SO 3 for 45min The copper in solution is determined by flame atomic absorption spectrometry,then content of oxide copper minerals is obtained Standard deviation is between 0 002 and 0 004,and relative standard deviation is 4 3%～4 5%
