【摘要】 浓度高于250mg/L的ClO2溶液用稀释光度法测定误差较大,本文采用某品牌高浓度ClO2便携式比色计直接测试高浓度ClO2溶液。该比色计测试量程宽(5-999mg/L),测试稳定性好(相对标准偏差S=0.5%),结果准确可靠,对操作场地和人员操作水平无特殊要求。该比色计不仅适用于高浓度ClO2溶液现场直接测定,还可方便地应用于ClO2活化过程动力学的研究。更多还原

【Abstract】 Large diviations exsit at the determination of high concentration of chlorine dioxide affter dilution chlorine dioxide solution which concentration is over 250mg/L.In this paper,direct determination of high concentration chlorine dioxide is proposed using HuanKai Portable Colorimeter of High Concentration Chlorine Dioxide.The portable colorimeter provide with wide test range(5-999mg/L),robust stability(S=0.5%),high precision and low request on venues and operator’s skill.The colormeter applies to not only on-site determine high concentration clorine dioxide,but also study of kinetics’ activation of clorine dioxide.更多还原
