一般描述
The chloride content of the water sample is depleted by means of sulfuric acid and an HCl absorber. The water sample is subsequently oxidized with a hot sulfuric solution of potassium dichromate, with silver sulfate as the catalyst. Residual chloride is masked with mercury sulfate. The concentration of green Cr3+ ions is then determined photometrically.
The chloride depletion method corresponds to DIN 38409-41-2.
The method corresponds to DIN ISO 15705 and is analogous to EPA 410.4, APHA 5220 D, and ASTM D1252-06 B.
The Spectroquant®Cell Tests come with prefilled 16 mm round cells and all the required reagents to perform the analysis according to the instruction leaflet provided.
All Spectroquant® Cell and Reagent Test Kits are equipped with the unique Live ID (2D barcode) , which allows seamless method recognition and contains essential information such as lot number, expiry date, and automatic calibration updates.
