摘要
本法采用碳酸钠.氧化锌混合试剂半熔后硫氰酸汞比色测定了土壤中微量的氯。实验并确定了各试剂的最佳加入量,方法相对标准偏差(RSD,n=12)为2%~9%。经国家标准物质验证,测定值与认定值基本符合。
This method is to measure trace chlorine in soil by mercury thiocyanate colorimetry using half-melted mixture of sodium carbonate and zinc oxide. It tested and determined the best addition of each reagent with RSD of 2%-9%. Checked by national standard reference material, the measurement fits certified value in general.
