latest Reading Material on nano silver infused shungite applications and efficacy

Introduction. The prospect of treating shungite in various ways to increase its absorption properties and increase the efficiency of water treatment during beverage production is shown. Materials and methods. Drinking water was prepared using shungite activated, activated and modified by nanosilver, activated, steam treated and modified by nanosilver. Photometric, spectrometric, chemical and potentiometric methods of analysis, theoretical generalization and comparison, a systematic approach were used in the work. Results and discussion. The parameters of aggregation of nanoparticles in water-glycerol medium, adsorption and sorptioncatalytic properties of shungite activated and nanomodified in various ways are investigated. Additional treatment of activated shungite with steam and nanosilver allows to increase its adsorption activity for iodine and for adsorption of acetic acid, alkalinity of water infusion up to 1.2 times and to provide stabilization of the redox potential of the prepared water at the level of + 90–100 mV. Steam treatment enhances part of the pores before diffusion and molecular sorption, and increases the adsorption activity of humic and fulvic acids by 40% by activated steam and silver nanoparticles by 40%. Waste water costs during the preparation of activated steam and nanosilver shungite do not exceed 20 relative volumes of wash water per volume of material, allowing the transparency of the prepared water is at least 99%. Pre-treatment shungite of steam before its activation with silver nanoparticles due to improving the wetting of the surface makes it possible to increase the duration of the filter cycle and the possibility of deepening the sorption of harmful water impurities: iron, manganese, nitrogen and organic compounds by 10–12%. Conclusions The use of shungite activated steam treated and modified by nanosilver provides increased efficiency of cleaning of harmful impurities an
