Optimization of Major and Trace Elements Determination in Acid Mine Drainage Water Samples by USN-ICP-OES
24 September 2015
Analysis can be from ppb to % levels, with the matrices quite variable leading to difficulties to matrix match and no suitable standards or CRM’s are available. There is also high dissolved solids and the technique of standard addition might cause trace element interferences. This poster shows that an in house standard choosing a Tinto river sample with similar matrix was suitably for spiked additions. Acid Mine Drainage (AMD) contains environmental oxidation of sulphides enrich residues from mine activities e.g. tailings, waste rock, mining and waste material.
