【摘要】 本研究用R5法制取ClO2 对医院污水进行消毒处理 ,针对碘量法测定剩余ClO2 时的不足 ,通过控制溶液pH值、加入稳定剂、活化剂和掩蔽剂的方法对其进行改进 ,实现了将溶液中ClO2 、Cl2 、ClO- 2 、ClO- 3区分测定的目的。实验表明 ,改进后的检测方法能够真实准确地反映溶液中剩余的ClO2 。更多还原

【Abstract】 In this paper,chlorine dioxide,produced from R 5 method,was used to treat hospital wastewater as a disinfectant.According to the shortage of the determination of remainder chlorine dioxide by iodimetric method,the method of determination was improved by controlling pH and using stabilizer, activator and masking agent.The respective determination of ClO 2,Cl 2,ClO- 2 and ClO- 3 in a solution was realized.The result shows that the improved method can reflect precisely chlorine dioxide of solution.更多还原
