| 中文摘要: |
| 报道了以银电极为指示电极,饱和甘汞电极为参比电极,在丙酮-氨水介质中,用硝酸银电位滴定法测定黄原酸钾的含量,滴定终点敏锐,方法简便、准确,相对标准偏差低于0.50%(n=5). |
| 英文摘要: |
| A novel method for determination of potassium ethyl xanthogenate in acetone-ammonia media by potentiometric titration, which employs the silver ion selective electrode as indicative electrode and the saturated calomel electrode as referred electrode, was developed. The test conditions were investigated. The experimental results under optimal conditions showed that the method was simple fast with keen titration end point. It has been applied to determine potassium ethyl xanthogenate with satisfactory results, the relative standard deviations didn’t exceed 0.50%. |
