中文摘要: |
常温下在H2C2O4-H2SO4介绍中,用50g/L硫脲(Tu)溶液可完全浸提含金硫化矿中Au,对金的浸取率可达99.8%,然后作用CL-P204萃淋树脂事集含金分解液中Au(Tu)2^+,结晶紫分光度法测定。方法用于硫化原生矿及含硫浮选精矿中Au的测定,所得结果与王水分解原子吸收法测定相符,其RSD(n=5)〈3%。 |
英文摘要: |
In the medium of H 2C 2O 4 H 2SO 4 gold in sulfurized minerals can be decomposed by 50 g/L of thiourea solution with 99.8% of leaching out efficiency for gold. Gold then can be concentrated by chromatography with CL P 204 resin and determined |
