Description

The determination ranges of the sulfate analyzer vary from 0.5 to 5000 mg/L SO42- using internal dilution module.

Method

This method is an adaptation of the turbidimetric method to measure sulfates. Sulfate ions are precipitated as barium sulfate with an excess of barium chloride. A conditioning reagent is added to maintain the barium Sulfate suspension. When the reagent is added to a sample containing Sulfate, it will cause turbidity in the sample. The absorbance (turbidity) intensity is proportional to the Sulfate concentration in the sample and is measured at 430 nm.
