| 摘要: |
| 采用毛细滴管数滴微型滴定法测定混合卤化物中的碘离子。毛细滴管数滴微型滴定法以自制的液滴体积为0.01~0.02ml的聚乙烯毛细滴管就地进行滴定,其主要仪器外形小巧、便于携带,滴定快速、准确,滴定剂用量仅为65~100滴。毛细滴管数滴微型滴定法的不确定度Urel (C)约为1.27%,与常量法相当。其分析样品的结果与常量法一致,相对标准偏差比常量法的略小。 |

| Abstract: |
| The capillary burette micro titration in counting drops is employed to determine iodine ions in the mixed halide solution. The polyethylene capillary burette of 0.01 to 0.02 ml drop size is used to carry through the titration. The titration dosage is 65 to 100 drops. The Urel (C) uncertainty is about 1.27%,similar to titrimetric analysis and accord with nation standard. The RSD is slightly smaller than the macromethod. |
