Method: photometric 0.50 - 50.0 mg/l SO₄²⁻ Spectroquant®

The method is analogous to EPA 375.4, APHA 4500-SO42- E, and ASTM D516-11.

This Spectroquant® Sulfate Reagent Test allows the accurate quantification of the sulfate content in aqueous samples.

Method applied: Sulfate ions react with barium ions to form slightly soluble barium sulfate. The resulting turbidity is measured in the photometer (turbidimetric method).

The Spectroquant® Reagent Test Kits contain highly stable, ready-to-use reagent mixtures to perform the analysis according to the procedure described in the accompanying instruction leaflet.
