Abstract
Mercury is one of the common heavy metal elements in coal gangue, and it is very important to detect mercury in view of environment risk control. In this work, we develop a rapid and simple detecting method of mercury in coal gangue based on anodic stripping voltammetry. Through a large number of experiments, operational parameters of anodic stripping voltammetry detection for mercury have been optimized, including working electrode, reference electrode, auxiliary electrode, electrolyte, scanning mode, stirring rate, enrichment potential, accumulation time, rest time, scanning potential and scanning rate. Our study provides a quick and accurate detection method for Hg(II) in coal gangue.
