一般描述
方法:比色法,靛酚蓝,使用比色卡和滑动比色器 0.2 - 0.4 - 0.6 - 1 - 2 - 3 - 5 mg/l NH₄⁺ MQuant®
该MQuant®铵测试(原MColortest®)适用于使用简单易用的比色卡进行比色法检测。测试对象包括未处理样品,因此即使是混浊和有色的水样也能用于分析。该测试检测诸如地下水和地表水、饮用水和水族馆用水中的氨离子和溶解氨。铵氮(NH4-N)部分以铵离子形态存在,部分为氨形态。两种形态之间存在pH依赖性平衡。
分析方法
在强碱溶液中,铵氮几乎都以铵形态存在,其可与氯化试剂反应形成一氯胺。该产物又会与百里酚反应生成蓝色的吲哚酚衍生物。由于空白试剂本身显黄色,测试液显黄绿色至绿色。通过匹配测试液颜色与比色卡值,可半定量测定铵浓度。
该测试可用于测定以下物质中的铵含量:
该测试不适用于海水。
