总碳分析仪如何检测水质?

余氯检测方法:

     对日益恶化的水源污染问题,自来水厂所采取的方式便是加入总碳分析仪江苏快3大量超过标准的氯(漂粉末)来消毒杀菌。加氯虽然能够杀死水中的各种病菌,但它一旦与水中的有机物结合,会因余氯或漂粉末的作用,产生大量有机氯化物(如三氯甲烷、二溴氯甲烷),危害人体健康。有机氯化物在动物体系的试验中已被确认为致癌物质。

     水的电导率与其所含无机酸、碱、盐的量有一定关系。当它们的浓度较低时,电导率随浓度的增大而增加,因此,该指标常用于推测水中离子的总浓度或含盐量。不同类型的水有不同的电导率。新鲜蒸馏水的电导率为0.2-2μS/cm,总碳分析仪江苏快3但放置一段时间后,因吸收了CO2,增加到2—4μS/cm;超纯水的电导率小于0.10/μS/cm;天然水的电导率多在50—500μS/cm之间,矿化水可达500—1000μS/cm;含酸、碱、盐的工业废水电导率往往超过10 000μS/cm;海水的电导率约为30 000μS/cm。电导率是衡量纯净水纯净程度的一项重要指标,反映了纯净水的纯净程度以及生产工艺的控制好坏。国家标准规定纯净水中电导率不得高于10μS/cm。
