| Abstract: | Two methods of determining Cr6 in drinking water and wastewater with high concentration of Cr6 are compared and analyzed in this paper.The experimental results show that(NH4) 2Fe(SO4) 2 titrimetric method is suitable for the measurement of the total Cr of wastewater with high concentration Cr6 and K2CrO7 method is suitable for the direct measurement and determination of high concentration of Cr6 . |
