目前,在金的各种分析方法中,一般都要用金的标准溶液(以下简称金标液).由于金在各种物料中多为微量或痕量组分,所以在分析过程中所需金标液的量很少.因此,一次配制金标液后往往可使用很长时间.金标液的准确度直接影响分析结果的准确度.考虑到金标液的昂贵,笔者认为,讨论一下如何配制和保存金标液这一问题,在实际应用上及经济上都具有一定意义. At present, gold in various analytical methods, usually with gold standard solution (hereinafter referred to as the gold standard solution.) Because of gold in many materials mostly trace or trace components, so in the analysis process required Gold standard solution volume is very small.Therefore, a time after the preparation of gold standard solution can often be used for a long time.The accuracy of the gold standard solution directly affects the accuracy of the analysis results.If gold standard solution expensive, I think, to discuss How to formulate and preserve the gold standard solution of this issue, in practical applications and have a certain economic significance.
