摘要
本法基于可定量测定K2Cr2O7和Cl-的反应产物Cl2这一原理,在用吸收装置吸收Cl2后,用碘量法测定余氯,从而消除氯离子的干扰。本法具有较高的准确度和精密度。
The method is based on the theory that K2Cr2O7 and Cl - can be detected quantitatively and Cl2 can be produced. When Cl2 is absorbed by absorption equipment, remained Chlorine can be detected by iodimetry, eliminating the disturbance of Cl- . It has high accuracy and preciseness.
