摘要
针对硫化物标准GB/T 16489-1996、GB/T5750.5-2023、HJ/T200-2005、SL89-1994、DZ/T0064.67-2021、HJ 1226-2021 中都含有用碘量法测定硫化物标准溶液的方法,对 1 000 mg/L硫化物标准溶液用以上标准中碘量法分别进行标定,通过结果分析,找到标准HJ 1226-2021 中影响硫化物标定准确性的原因,并提出解决方案.
Abstract
The sulfide standards GB/T 16489-1996,GB/T 5750.5-2023,HJ/T 200-2005,SL 89-1994,DZ/T0064.67-2021,HJ 1226-2021 contains a method for determining sulfide standard solutions using the iodometric method.By calibrating the 1 000 mg/L sulfide standard solution using the iodine method in the above standards,and through result analysis,the reasons affecting the accuracy of sulfide calibration in standard HJ 1226-2021 were identified,and solutions were proposed.
