STUDY OF THE EFFICIENCY OF USING AGGLOMERATED ACTIVATED CARBON FOR THE PURIFICATION OF WATER-ALCOHOL SOLUTION
Abstract
The use of activated carbon for industrial use in vodka production is associated with the need for continuous quality improvement. Improvements in the methods of production, activation or modification of activated carbon play a significant role. The article presents the results of a study of agglomerated activated carbon in comparison with traditional granular activated carbon in order to improve the method of purification of water-alcohol mixtures in the production of vodkas and special vodkas. During the research, standardized organoleptic, physicochemical, gas chromatographic, capillarophoretic, spectrophotometric methods of analysis were used, theoretical generalization and comparison of results, and a systematic approach. A comparative assessment of sorption materials used for purification of water-alcohol mixtures was carried out, experimental studies of their sorption and catalytic activity were carried out. Physicochemical indicators were established and it was determined that the studied agglomerated activated carbon has a greater adsorption capacity, is more durable and low-ash compared to the control sample of crushed wood activated carbon. The positive effect of agglomerated activated carbon on the purification of the water-alcohol mixture in the production of vodkas and special vodkas was shown. It was found that purification with the studied agglomerated activated carbon allows to increase the purification effect, increase the tasting assessment by removing unwanted organic microimpurities and improve the transparency of the water-alcohol mixture in comparison with the original water-alcohol mixture. The increase in the purification efficiency by the difference in the oxidation of the water-alcohol mixture after treatment with agglomerated activated carbon allows to conclude about the feasibility of using it in the technology of preparing vodkas and special vodkas.
