Process for adsorbent obtaining and process for demetalation of wine-making products with utilization thereof

Abstract

The invention refers to the wine industry, in particular to a process for adsorbent obtaining and to a process for demetalation of wine-making products with utilization thereof.According to the invention, the process for adsorbent obtain of perlite at a temperature of 120…160°C during 1…2 hours, comminution, carbonization in isothermic conditions at a temperature of 450…500°C during 2…3 hours in nonoxidizing atmosphere and electrochemical activation in 3…5% solution of potassium or sodium orthophosphate in the anodic chamber of the diaphragm cell, the anodic current density being of 2…3 A/dm3 during 5…10 min.The process for demetalation of wine-making products with utilization of the adsorbent obtained by said process is carried out with adsorbent fluidization in a dose of 6…10 g of adsorbent per 1 g of iron and/or copper compounds during 15…20 min.The result consists in increasing the different and in intensifying the process for demetalation of wine-making products.
