一般說明

MQuant®氯测试（原MColortest®）可用于游离氯的测定。

该测试可用于
  • 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）反应形成红紫染料。通过目视比较测量溶液的颜色与色卡的色场，可以半定量地测量氯浓度。
印染独特的光亮及其精细的颜色等级可获得精准的分析结果，即使在浓度范围的下限。测量范围广，长试管亦能快速响应。原始试剂盒可通过包含所有试剂的补充包1.14977延长其使用寿命，是一种特别实惠的生态系统产品。 
（游离氯）方法：使用色卡和带有长试管的比色架进行比色，DPD 0.010 - 0.025 - 0.045 - 0.06 - 0.08 - 0.10 - 0.15 - 0.20 - 0.30 mg/l Cl₂ MQuant®

應用

  • 3,3′,5,5′-tetramethylbenzidine as multi-colorimetric indicator of chlorine in water in line with health guideline values.: This study demonstrates the use of 3,3′,5,5′-tetramethylbenzidine as a colorimetric indicator for detecting chlorine levels in water, providing a cost-effective and simple method for ensuring water safety in compliance with health guidelines (Palladino et al., 2020).
  • Analysis of free chlorine in aqueous solution at very low concentration with lateral flow tests.: Investigates the effectiveness of lateral flow assays for the quantification of free chlorine in water, highlighting their potential for quick and accurate chlorine testing in field settings (Schwenke et al., 2019).
  • Improved residual chlorine test; the ortho-toluidine: arsenite method for testing water for true, false and chloramine residuals.: Describes a methodological advancement in measuring different forms of chlorine residuals in water, enhancing the accuracy of water quality assessments (GILCREAS FW, 1948).

How to Prepare a Standard for Free Chlorine Analysis

AQA Standard for free chlorine - Preparation of a standard solution for free chlorine - Preparation of a stock solution of free chlorine: First prepare a 1:10 dilution using a sodium hypochlorite solution containing approximately 6 - 14 % of active chlorine. For this pipette 10 ml of sodium hypochlorite solution into a calibrated or conformity-checked 100-ml volumetric flask and then make up to the mark with water for analysis.
