摘要
用工业氯化钠为原料 ,通过控制PH值 ,添加辅料 ,进行精制提纯 ,浓缩结晶 ,得到符合国家质量标准的分析纯氯化钠试剂 ,可实现产品一高 (质量 )二率 (合格率、回收率 ) 。
Purpose To improve appreciation and benefifial result. Methods To use industrical sodium chloride as raw material by means of controlling PH value,cleanup and concentrating crystals . Result To obtain standard analyse refine sodium chloride reagent accordea with national quality . Conclusion To bring about products of one higher (quality)two rates (percent of pass,recovery ratio).
