Uncertain Evaluation of Degree of the Measurement of Total Hardness of WaterLIANG Jing-bo , et al 1 .Zibo Environmental Monitoring Station, Zibo 255040, ChinaAbstract:Uncertain degree is evaluated to adopt EDTA titrimetric law to measure total hardness of water quality. Fully consider measuring such impacts on measurement of the course as the disposition and titration of repetitiveness, standard solution, etc., calculate water total measurement of hardness relative to formates standard confirm degree as 1.81 × 10^-3 .[著者文摘]
