描述

一般說明

含氯消毒剂的使用最为广泛。它们特别适用于饮用水和游泳池水的消毒。MQuant^®氯测试（正式名称为MColortest^®）可用于测定以下水中的游离氯和总氯

• 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
• 消毒液

此测试不适用于海水。

分析方法
在弱酸性溶液中，游离氯与二丙基对苯二胺（DPD）反应生成红紫色染料。在存在碘化钾的情况下，在该反应中还测量了结合的氯。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。
使用补充包1.14977，原始测试套件可以使用很长时间，使其成为一个特别经济的生态系统。

（游离氯）方法：比色法，DPD，采用色盘型比色器 0.25 - 0.50 - 0.75 - 1 - 2 - 4 - 8 - 10 - 15 mg/l Cl MColortest^®

應用

• 3,3′,5,5′-tetramethylbenzidine as a multi-colorimetric indicator of chlorine in water in line with health guideline values: This study focuses on using 3,3′,5,5′-tetramethylbenzidine as an indicator for the presence of chlorine in water, providing a method to ensure compliance with health guidelines through a visual and straightforward test (Palladino et al., 2020).


• Analysis of free chlorine in aqueous solution at very low concentration with lateral flow tests: This paper introduces a method for testing free chlorine concentrations in water at very low levels using lateral flow assays, which are crucial for monitoring water quality and ensuring safety standards (Schwenke et al., 2019).


• Some factors influencing the stability of Sterilox, a super-oxidised water: This article, while focused on the stability of Sterilox as a disinfectant, deals with the broader context of using chlorine solutions in settings requiring stringent sanitation measures, highlighting the importance of regular chlorine testing to ensure efficacy (Rossi-Fedele et al., 2011).
