| 摘 要： | 硫酸盐-氧化亚铜-石英砂直接热解法需要设置分离SO2、H2O和CO2的冷阱。研究表明H2O和CO2主要来自试剂石英砂的气液包裹体。采取石英砂预处理措施能大大减少制样过程引入的H2O和CO2。改进后的制样系统简单、易操作,且与硫化物同位素样品制备兼容。

| Abstract: | The previous method of directly thermal decomposition of sulfate-Cu2,O-SiO2 needed the two traps for separation of SO2 from H2O and CO2. Our experiments suggest that a great of fluid inclusions existed in the reagent of silica sand, either natural or artificial, is the main source of H2O and CO2 and the pretreatm ent of silica sand can reduce greatly the amount of H2O and CO2 in the sample preparation. So that, our system for the preparation of sulfate samples becomes simpler, easer and compatible to the preparation of sulfide samples |
