摘要
A method and technology for the deposition of strongly bonded high-disperse manganese dioxide onto the external surface of clinoptilolite grains is developed. The optimal conditions for the application of thus prepared material for the purification of artesian water are determined. A two-stage process of water purification is proposed, which involves usual clinoptilolite filter at the first stage to remove the main amount of iron, and the filter with modified clinoptilolite on the second stage to remove the residual iron and bivalent manganese ions. The proposed technology of preparation and application of modified clinoptilolite is tested in industrial conditions.
