Water quality — Determination of selected parameters by discrete analysis systems — Part 2: Chromium (VI),fluoride, total alkalinity, total hardness, calcium, magnesium, iron, iron(II), manganese and aluminium with photometric detection

Abstract

This document specifies methods for the automatic determination of chromium(VI), fluoride, total
alkalinity, total hardness, calcium, magnesium, iron, iron(II), manganese and aluminium with
photometric determination using a discrete analysis system. The field of application is water (ground,
potable, surface, waste, eluates and boiler water). The method can also be applied to marine waters with
matrix matching of standard and control solutions. Note that some parameters, notably iron, manganese
and aluminium and possibly chromium(VI), calcium and magnesium may not be completely quantified
if the sample contains particulates. Samples can be digested in acid, as long as the buffering capacity of
the reaction mixture is not exceeded. Such procedures are beyond the scope of this document, which is
best suited to the determination of dissolved metals following on-site filtration.
