测定磷灰石中氧化镁时分解试样的溶剂多用王水或碱熔[1],操作费时且气味大,为此,实验用KCl-HNO3混合溶剂溶样的方法。结果表明,本法具有简便、快速、成本低、较环保等特点,经与碱熔样测定MgO结果相比较,令人满意。
Determination of apatite magnesia when the decomposition of the sample solvent and more use of aqua regia or alkali melting [1], the operation time-consuming and odor, for this experiment KCL-HNO3 mixed solvent solvent sample method. The results show that this method is simple, rapid, low cost, more environmentally friendly and other characteristics, compared with the results of MgO determination of alkali fusion samples, satisfactory.
