Power expenditure for water purification to remove arsenic(V) was determined. The processes and kinetics of purification in an electric-discharge reactor with a metallic (aluminum or iron) charge were investigated. The purification mechanisms based on the adsorption of arsenic(V) on a fresh surface of hydroxides formed through dispersion and subsequent oxidation of a charged metal were suggested. Rate equations corresponding to the experimental data and to these mechanisms were given.
