Heavy metals occur naturally in soils, but human activities lead to greater levels of heavy metals contamination in soils and to the environment. Metals in water and wastewater may be present in any or all of the following forms, each of which may require determination: (a) Dissolved (filterable) metals: Those metals which pass through a 0,45 ym membrane filter. etc.) The aim of this study is to determine the measurement uncertainty of spectrophotometric determination of Cr(6+) in water. Spectrophotometry is essentially a trace analysis technique and is one of the most powerful tools in chemical analysis. After wet digestion, the samples were analysed using atomic absorption spectrophotometer – coupled with a hydride generator for As and CV-AAS for Hg.
