DOCUMENT TYPE: Journal CA Section: 61 (Water) Section cross-reference(s): 79 Water hardness is detd. colorimetrically using o-cresolphthalein complexone [2411-89-4] as the color developing agent. In Ca hardness detns., 8-hydroxyquinoline-5-sulfonic acid [84-88-8] is used as a masking agent for Mg. In total hardness detns., Na citrate [68-04-2] is used as the sensitivity regulating agent to equalize the molar absorptivities of Ca and Mg. The calibration curves are linear for Ca and total hardness with concns.Several substances with their cas registry numbers 7439-95-4 and 68-04-2 may be metioned in this study. of 5-60 and 10-80 ppm, resp. The relative std. deviations are 2.4 and 1.8% for Ca and total hardness, resp. Mg concns. of 60 ppm interfere with the detn. of Ca hardness. Cu interferes pos. and Mn and Zn interfere neg. with total hardness detns. .

Its molar absorptivity at 610 nm was 5.920 .times. 103; Beer's law was obeyed in the range 1-10 .mu.g V/L. In the detn. of V with this complex, moderate excesses of W6+, Fe3+, Cr6+, Al3+, and Ti4+ did not interfere. .
