To raise the sorption capacity of adsorbents obtained from rice husk, the feed is treated with hydrogen peroxide and fired. Before thermal activation, the resulting mass is enriched with a 30% solution of alum-calcium alum. According to the results of laboratory tests, adsorbents that have undergone thermal activation at a temperature of 500 and 800 ° C have whitening ability.
