| 摘 要： | 沉积的碳酸盐岩石主要是由方解石（CaCO3）和白云石（CaMg[CO3]2）的碳酸盐矿物组成。对于碳酸盐岩石中二氧化碳、氧化钙、氧化镁的测定,在例行的分析中,都是单独取样,分别以吸收重量法或容量法测定二氧化碳,以草酸铵-高锰酸钾容量法测定钙,而镁则根据 CO2与 CaO 的含量之差数来求得,或用氢氧化钡标准溶液使镁沉淀,于滤液中用盐酸滴定过量的氢氧化钡而测定镁。为了缩短分析时间,简化操作手续,节省试剂,作者提出了在以酸碱容量法测定 CO2后,在同一份样品中,以 E.D.T.A.络合滴定法进行钙和镁的连续测定方案。通过二年来的实践证明是完全可行的。它的特点是比较经济准确简便快速,因此具有一定的实际意义。

| Abstract: | In the present paper,a rapid method for continuously determining CO2,CaO and MgO of carbonate rocks is suggested.This method is simple,rapid,precise and economic. As compared with the weight method,the relative error is reduced to less than 0.5%. Six to eight samples can be analyzed in a day. The present method is more useful for the analysis of limestone and dolomite used as raw materials in the construction and metallurgical industry. |
