D 516 - 59 T Tentative Methods of Test for Sulfate ion in Industrial Water and Industrial Waste Water

Abstract

(a) These methods cover the determination of sulfate ion in industrial water and industrial waste water. Three methods are given as follows: Sections Referee Method (Gravimetric Method) 5 to 11 Non-Referee Method A (Turbidimetric Method) 12 to 20 Non-Referee Method B (Volumetric Method) 21 to 31 (b) The Referee method is a primary measure of sulfate ion in all industrial water. The Non-referee methods are less time-consuming but often more liable to interference than the Referee method. They are particularly useful in the lower sulfate range, below 20 ppm SO4−−.
