摘　　要：介绍了氯化钾电导率标准溶液的研制。选择优级纯氯化钾为原料,经提纯后,配制成电导率标准值为84μS·cm-1的电导率标准物质。采用与一级标准物质比对的方法进行定值、均匀性检验及稳定性检验。研制的电导率标准物质,均匀性良好,稳定性达一年,获得国家二级标准物质证书。The development of a standard conductivity solution of Potassium chloride was described. The purified reagent potassium chloride was used as raw material, the 84 μS·cm^-1 standard conductivity solution was obtained prepare. It was compared with conductivity standard substance to determine the conductivity value, test uniformity and stability. The standard conductivity solution is uniformity, stability over one year. The national secondary standard substance certificate was obtained.
