| 摘 要： | 四苯硼钠—季铵盐容量法测钾含量,实验原理要求应使分析样中钾离子的含量控制在5mg左右。本实验通过控制分析样中钾含量偏离5mg与控制在5 mg左右时进行误差分析,发现分析样中钾含量低于5mg时,化验结果将偏大,高于5mg时化验结果将偏小,相对误差都超过了1%。

| Abstract: | The four benzene boron - quaternary ammonium salt capacity measured potassium sodium content, experimental principle requirements should make analysis of potassium content in the sample control at about 5 nag. This experiment by controlling the potassium content in sample analysis was from 5 mg and control about 5 mg in error analysis, found below 5 nag potassium content in the sample analysis, the results would be larger, higher than 5 mg test results would be small, the relative error was more than 1%. |
