本文针对用氢氧化钠和银坩埚处理试样制备试样溶液的方法进而用滴定法测定Si O2、Fe2O3、Al2O3、Ca O、Mg O的研究。通过对钢渣、尾矿试样的测定,总结出测定常见工业废料中Si O2、Fe2O3、Al2O3、Ca O、Mg O含量的普适方法。该方法具有准确度高、易操作、设备简单等优点。通过实验原理、步骤和结果的探讨,为实验室测定Si O2、Fe2O3、Al2O3、Ca O、Mg O提供了一个快速、方便、易于推广的方法。
In this paper, sodium hydroxide and silver crucible sample preparation of the sample solution and then titration determination of Si O2, Fe2O3, Al2O3, CaO, MgO research. Through the determination of steel slag and tailings samples, a universal method for determining the contents of Si O2, Fe2O3, Al2O3, CaO and MgO in common industrial wastes is summarized. The method has the advantages of high accuracy, easy operation and simple equipment. Through the discussion of experimental principle, procedure and results, it provides a rapid, convenient and easy-to-extend method for laboratory determination of Si O2, Fe2O3, Al2O3, CaO and MgO.
