CI-是锅炉水质处理重要的监测指标之一。通过测定CI-的含量,可以间接地测算出锅水中溶解固形物的含量,可以用于监控固定床软化水设备清洗过程的终点。关于CI-的测定方法,GB/T 1576《工业锅炉水质》附录G已介绍非常清楚。在此阐明的CI-的测定方法与GB/T 1576附录G所不同的是AgNO3标准溶液的浓度表示不是滴定度,而是摩尔浓度,测定时所使用的指示剂是K_2CrO_4而不是铁铵矾指示剂,也不用硫氢酸铵标准溶液滴定。操作简单易行、易懂,特别适用使用固定床软化水设备的用户。
CI- is one of the important monitoring indicators for boiler water quality treatment. By measuring the content of CI-, the amount of dissolved solids in the pot water can be indirectly measured, which can be used to monitor the end of the fixed bed demineralized water equipment cleaning process. Determination of CI-, GB / T 1576 “Industrial Boiler Water Quality” Appendix G has been very clearly introduced. The method of determination of CI- is different from that of GB / T 1576 Appendix G. The concentration of AgNO3 standard solution indicates not titer but molarity. The indicator used in the determination is K 2 CrO 4 instead of Ammonium Ammonium Indicator Agent, nor ammonium hydrogen sulfate standard solution titration. Easy to operate, easy to understand, especially for users of fixed bed demineralized water equipment.
