| Abstract: | A possibility to utilize fly ash (FA) formed at coal-fired power plants as a cheap adsorbent for the purification of wastewater
containing azo dyes methylene blue (MB) and methyl red (MR) was considered. The effect of an FA additive on the adsorption
capacity of active carbon was studied. The efficiency of FA as an adsorbent for the purification of aqueous solutions from
MB and MR was shown. The adsorption is also fairly efficient when active carbon is partially replaced by FA.
