Abstract

The purpose of this study was to evaluate the effectiveness of the process of removing arsenic in liquid waste that has been generated by a gold mineral treatment plant from the central region. The Molybdenum blue method by visible ultraviolet spectrophotometric (UV) was used. Linearity, quantification limit, detection limit and precision were determined as performance parameters. All evaluated validation parameters met the regulated requirements; this fact ensures greater reliability in the analytical laboratory work. Finally, it was demonstrated that although the method is effective for metal precipitation, it does not entirely remove the arsenic.

Keywords: arsenic, molybdenum blue, characterization, waste, validation.
