摘要
作者自行设计酸分解反应器,与国产YZYT型电导法测碳仪连接,拟定了酸分解—电导法测定岩矿中碳酸盐的CO_2。本法操作简便、成本低廉、灵敏度较高(检出限为0.018mgCO_2),RSD一般不超过4％。方法已用于多种地质试样中CO_2的测定,结果满意。
The reactor was planed for decomposing geological samples with acid, and connected with Model YZYT carbon analyzer. On the basis of the plan,, an acid decomposition-conductmetric method is proposed to determine CO2 in carbonate form in rocks and minerals.
The detection limit is 0.018mg CO2 with RSD(n = 6) =1-4% for 0.1-16% CO2. The method is simple and cheap and has been applied to determine CO2 in various geological samples with satisfactory results.
