Purification of water by electrocoagulation with an alternating asymmetrical current for stripping voltammetry

The influence of the flow velocity and the current density on the degree of purification of water by electrocoagulation with an alternating asymmetrical current has been studied. It has been demonstrated that under optimum conditions at pH/sub c/ 11.0-11.5 the residual metal content in the purified water drops to the level n x 10/sup -4/ g/ml; this allows its use in the practice of stripping voltammetry.
