| Abstract: | Dyes are used in various sectors like textile, paper and dyeing industries which discharge hazardous coloured dye effluents. The ability of heterogeneous mixture of alumina and clay (1:2) to remove the colour of dyes has been investigated. It was found that low adsorbate concentration, small particle size of adsorbent, temperature 25°C and pH 7.2 of the medium favour the removal of dye from aqueous solution. The dynamics of adsorbate transport from bulk to the solid phase has been studied at different temperatures. The applicability of Langmuir isotherm suggests the formation of monolayer coverage of dye molecules on the outer interface of the adsorbent. The thermodynamic studies or dye-alumina clay system indicates spontaneous and exothermic nature of the process. |
