The effects of organic anions on alkalinity measurements in organic-rich waters in Nova Scotia [electronic resource] / by Mary E. Thompson. Burlington, Ont. . : Aquatic Physics and Systems Division, National Water Research Institute, Canada Centre for Inland Waters, 1986. 11, [9] p. : ill. NWRI contribution ; 86-9 "March 1986". "Control No. AP240". Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographical references. "The realization of the presence of reactive and titratable organic anions in the strongly colored waters of Nova Scotia has called for reexamination of some of the analytical methods applied to such waters. This report discusses the effects of organic anions on the established Gran alkalinity titration procedures. The author concludes that the organic anion interference is in most cases minimal, and recommends that the alkalinity procedures be continued, that sulfate continue to be analyzed by both ion chromatographic and colorimetric methods, and that some direct measurements of dissolved carbon dioxide be made"--Exec. summary.
