Evaluation of SO4 data compatibility and approaches for salvaging historical data / by V. Cheam, A.S.Y. Chau, and S. Todd. : En13-5/85-117E-PDF
"The compatibility and reliability of colorimetric and chromatographic SO4 data were evaluated. The multiple standard addition technique was applied to numerous natural and humic-acid fortified waters. A total of more than 20 different waters was used, in which the colour ranged from 50 to 440 H.U. and the organic carbon from 0.7 to 20 ppm. For the first time, it was demonstrated that Ion Chromatography (IC) data on organic-contaminated coloured waters are reliable.It was also confirmed that the Methyl Thymol Blue (HTB) colorimetric data were biased high. An approach for salvaging historical colorimetric data was found and briefly discussed"--Abstract.
