水中 ClO2、Cl2、ClO2- 及ClO3- 的连续碘量法测定
Determination of ClO2、Cl2、ClO2-and ClO3- in Water by Using Continuous Iodimetry
【摘要】 通过大量的试验确定了碘量法连续测定水中ＣｌＯ２、Ｃｌ２、ＣｌＯ－２和ＣｌＯ３－的适宜条件。该方法的准确度、精密度和灵敏度都较好。其方法的回收率：ＣｌＯ２为９６７８％；Ｃｌ２为９８１７％；ＣｌＯ－２为９７２８％；ＣｌＯ３－为１０３３１％。变异系数：ＣｌＯ２为１５２％；Ｃｌ２为２３７％；ＣｌＯ２－为２４３％；ＣｌＯ３－为３５６％。最低检出限：ＣｌＯ２为００５０ｍｇ／Ｌ；Ｃｌ２为００５０ｍｇ／Ｌ；ＣｌＯ２－为００５０ｍｇ／Ｌ；ＣｌＯ３－为０５００ｍｇ／Ｌ。
【Abstract】 The optimum conditions are reported for the determination of ClO2、Cl2、ClO2- and ClO3- by using continuous iodimetry The precision, accuracy and sensitivity are fairly good The rate of recovery is: ClO 2: 96 78%; Cl 2: 98 17%; ClO 2 -:97 28%; ClO3 -:103 31%, respectively The coefficient of variation are: ClO 2: 1 52%; Cl 2:2 37%; ClO 2 -:2 43%; ClO 3 -:3 56%; respectively The detection limit are: ClO 2: 0 050mg/L; Cl 2: 0 050mg/L; ClO 2-: 0 050mg/L; ClO 3 -:0 500mg/L;respectively
