Technology of activated charcoal (AU-L) tablets and their sorption capacity determination

A new technology is developed for the production of activated charcoal (AU-L) tablets from cotton lignin, a readily available local raw plant material. The physicochemical and technological properties of the parent substance (powder) have been studied and the optimum composition of tablets has been determined. The best technological characteristics of both the initial mass and the ready-to-use tablets are achieved for the composition involving a 3% methyl cellulose gel as a binding component and microcrystalline cellulose as a filler. The qualitative characteristics of AU-L tablets have been studied and their sorption capacity has been determined. The new technology will be implemented at the Tashkent Pharmaceutical Plant (Uzfarmprom Company). © 2007 Springer Science+Business Media, Inc.
