摘要
综合分析影响测定水硬度的因素,提出了降低或避免对测定结果产生影响的方法,并对干扰因素的消除方法做了总结,以对化验室中水硬度的测定提供依据,达到提高测定结果准确度的目的。
Factors influencing the determination of water hardness were analyzed synthetically,and solutions to reduce or avoid the influence on the test results were given,and the elimination methods for the interference factors were summarized,which provided base for the water hardness test in the laboratory and the purpose of increase on the test result accuracy was reached.
