一般描述
MQuant®氯测试（过去称为MColortest®）可用于通过液体试剂测定游离氯和总氯。
该测试可用于
此测试不适用于海水。
分析方法
在弱酸性溶液中，游离氯与二乙基对苯二胺（DPD）反应形成红紫色染料。在存在碘化钾的情况下，在该反应中还测量了结合氯。通过目视比较测量溶液的颜色与色盘色域，可以半定量测量氯浓度。
该测试基于透射光法对显色反应进行评估。因此，即使对于浑浊和有色水样，也可以进行分析，无需任何准备。
色盘由耐用、耐晒的塑料材质制成，适用于工业领域和潮湿的环境。
原始试剂盒可通过包含所有试剂的补充包1.14979延长其使用寿命，是一种特别实惠的生态系统产品。
该测试可用于
- 地下水和地表水
- 饮用水和矿泉水
- 水产养殖水
- 废水
- 电镀废水
- 消毒溶液

应用
- Water Treatment and Disinfection: Chlorine testing is crucial for ensuring the safety and effectiveness of water disinfection processes. Accurate measurement of free chlorine and total chlorine levels is essential to maintain appropriate disinfection while minimizing the formation of harmful disinfection by-products (DBPs). Recent studies have focused on the kinetics of chlorine reactions in seawater and their impact on biocidal effectiveness and environmental safety (Kinani et al., Critical Reviews in Analytical Chemistry, 2022).
- Environmental Monitoring: Chlorine testing is used to monitor chlorine levels in various environmental matrices, such as rivers, lakes, and wastewater. This is essential to assess the impact of chlorination on aquatic ecosystems and to ensure compliance with environmental regulations. Advanced chromatographic and mass spectrometric techniques are employed to speciate chlorine-produced oxidants and their by-products in seawater (Roumiguières et al., Critical Reviews in Analytical Chemistry, 2023).
- Public Health and Drinking Water Safety: Ensuring the safety of drinking water is a primary concern. Chlorine testing helps to maintain the right balance of chlorine for effective pathogen control while avoiding excessive chlorination that could lead to health risks. Analytical methods, including titrimetric and colorimetric methods, are used to measure residual chlorine in drinking water to ensure it meets safety standards (Ko et al., Chinese Journal of Analytical Chemistry, 2022).
- Industrial Applications: Chlorine testing is essential in various industrial processes where chlorine is used, such as in the production of paper and textiles, and in cooling water systems. Accurate monitoring of chlorine levels helps in optimizing these processes and ensuring compliance with safety and environmental regulations (Kinani et al., Critical Reviews in Analytical Chemistry, 2022).
- Photochemical Degradation Studies: Chlorine testing is also used in research studies involving the photochemical degradation of pollutants. For example, the use of UV/free chlorine processes in degrading pharmaceuticals in aqueous solutions has been investigated using response surface methodology to optimize conditions for maximum efficiency (Arman et al., International Journal of Environmental Analytical Chemistry, 2022).
