水质中总硬度的检测方法

Test method for total hardness in water

目的建立快速检测水质总硬度的检测方法。方法基于工厂实际生产需求,采用快速试纸条方法对工厂内使用的配料用水、清洗用水、源水的总硬度进行检测,并通过方法优劣性分析、适用性验证、准确性验证、精密度验证等维度进行分析总结,同时与国标方法进行结果差异对比。结果通过对4个维度的实验证明,快速试纸条法检测结果与国标方法对比无显著差异。结论本研究中试纸条快速检测方法,可以满足生产过程中配料用水、清洗用水、源水的质量检测。

Objective To establish a rapid test method for detecting the total hardness of water quality.Methods Based on the actual production requirements of the factory,the total hardness of the water used for batching,cleaning and source in the factory was measured by the rapid strip test method,the method was analyzed and summarized through the advantages and disadvantages analysis,applicability verification,accuracy verification and precision verification,and the results were compared with the national standard method.Results There was no significant difference betweenthe rapid strip method and the national standard method by the verification of the four dimensional experiments.Conclusion The rapid strip test method in this study can meet the quality test of batching water,cleaning water and source water in the production process.
