| 摘 要： | 本文报道采用示波极谱滴定法,在含1.0g KCl的水溶液中,用0.05mol/L NaOH标准液对朴尔敏及其制剂进行滴定,以示波极谱图的切口出现指示终点。该法操作简便、迅速,平均回收率为100.3%,CV%=0.21‰(n=8)。 |
| 关 键 词： | 朴尔敏 示波极谱滴定 含量测定 |

| Abstract: | Here tries the titra-tion of oscilloscope polarogram. That isin the content 1.0g kCl water solution,to use 0.05 mol/L NaOH in raw chlorp-henamini maleas and its preparationdirectly instead of indicator. With thebreak appearing on the oscillosco-pe polarogram picture, that indicatesthe end of the titration. Its result willbe very accurate. The average rate ofrecovery is 100.3% ev%=0.21 (n=8).And the destination is sudio-visual, themanipulation is simple, swift and sens-itive. |
