Chromium compounds can be present in industrial waste waters in trivalent form [chromium(III) ions] and in hexavalent form (chromate and dichromate ions). In order to determine the total chromium all other valencies must be oxidised to chromium(VI). Each test kit is equipped with a detailed description.
