Sulfate in colored waters : investigation of methodologies, data reliability, and approaches for salvaging historical colorimetrice data / by V. Cheam, A.S.Y. Chau and S. Todd.: En13-5/85-95E-PDF
"In the study of acid rain, there has been a great deal of discussion and concern over the analysis of sulfate particularly in coloured waters. This study was carried out at the request of WQB Headquarters, to investigate the validity of colorimetric and ion chromatography methods for determining SOQ in coloured water. The study examines in detail several important aspects of the analysis of sulfate in coloured waters. These aspects are analytical methodologies, data reliability, and ways to salvage historical colorimetric data. The data demonstrate that ion chromatography results on organic-contaminated coloured waters are reliable. The study further shows that the colorimetric data are biased high and that it is possible to salvage these types of data through the use of curves having specified amount and nature of organic-matter. This approach provides a sure way to correct the historical data and thereby permit data users to interpret the data with confidence"--Management perspective, p. i.
