Adsorption of dyestuffs from aqueous solutions with activated carbon I: Equilibrium and batch contact-time studies

The ability of one activated carbon to remove dyestuffs from aqueous solutions has been investigated. The range of dyestuffs includes acidic, basic, disperse and direct dyes, and several factors have been studied, namely, agitation, initial dye concentration, adsorbent concentration, adsorbent particle-size range, dye solution temperature, pH of solution and salt concentration.
