Spectroquant® Sulfide Photometric Test 0.020 – 1.50 mg/l S²⁻ [220 Tests]

Description

Method
In aqueous solutions of sulfides a pH-dependent equilibrium exists between dissolved hydrogen sulfide (H2S), hydrogen sulfide ions (HS-), and sulfide ions (S2-). In the acidic range, in which practically only dissolved
hydrogen sulfide is present, this reacts with dimethyl-p-phenylenediamine and iron(III) ions to form methylene blue. This is determined photometrically.
The method is analogous to EPA 376.2, APHA 4500-S2- D, ISO10530, and DIN 38405-26.
