Hydrochloric acid is an important basic chemical widely used in the industry. The largest consumption for hydrochloric acid is for steel pickling, ore processing, oil well acidizing, but it is also used in food manufacturing as an acid buffer, for cleavage of proteins or during the processing of drinking water. The specific application ultimately determines the required hydrochloric acid product quality.
This report describes the methodology for the analysis of trace metal impurities in hydrochloric acid. It presents typical detection limits for a selection of relevant elements and includes studies on accuracy via the analysis of a control sample.
