描述

一般說明

亚硝酸盐天然存在于土壤，水和食物中，定期测试其浓度对于许多应用至关重要。通过MQuant^®亚硝酸盐测试（正式名称为MColortest^®），可以密切监测饮用水和地下水以及加工、废物或水族馆水中的亚硝酸盐。该测试可用于：

• 地下水和地表水、海水
• 饮用水和矿泉水
• 水产养殖水
• 锅炉及锅炉给水、冷却水
• 废水和电镀废水
• 经过适当样品预处理的食品
• 适当样品预处理后的土壤

分析方法
在酸性溶液中，亚硝酸根离子与氨基磺酸反应形成重氮盐，重氮盐又与N-（1-萘基）乙二胺二盐酸盐反应形成红紫色偶氮染料。通过目视比较测量溶液的颜色与色盘色域，可以半定量测量亚硝酸盐浓度。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。

方法：采用色盘型比色器进行比色 0.1 - 0.2 - 0.4 - 0.6 - 1.0 - 1.8 - 3.0 - 6.0 - 10 mg/l NO MQuant^®
