National interlaboratory quality control study no. 33 : sulphate in coloured waters / V. Cheam and A.S.Y. Chau. : En36-508/75E-PDF
"This report describes an interlaboratory comparison study for the analysis of SO4 in organic contaminated coloured waters. Some 70 Canadian laboratories participated in the analysis of five unpreserved water samples. Because of the interference from coloured matter in the waters, some methodologies, in particular the methylthymol blue colorimetry, were identified as producing results that were biased high. Some other methodologies performed well, particularly ion chromatography"--Abstract.
