对锑浸出量测定法修订的建议

Recommendations of Determination Method for the Leaching Amount of Antimony

发现了现有国家标准锑浸出量的测定方法存在系统误差。基于试验原理,探讨了误差产生的原因,并对现有国家标准方法进行了适当改进,如保证样品与对照品测定体系中的盐酸浓度相同,且样品与对照品的反应体积一致。修订后的方法可用于锑的测定。

Some systematic errors were found in the current standard determination method for the leaching amount of antimony. The cause of the systematic error was discussed based on the experimental principle. Some recommendations were made, for example, to assure the concentrations of hydrochloric acid as well as the system volumes were same both in the sample and the reference determination systems. The method after amending was suitable for the determination of antimony.
