Item Decolourization of Reactive Dyes in Aqueous Solution Using Selected Agro Waste(2015-03) Emima Priscilla, V; Vasugi Raaja, NItem Removal of Selected Reactive Dye F R O M A Q U E O U S So L U T Io N Using Wheatbran(2016) Kalaiarasi, K; Emima Priscilla, VAdsorption is a potent method lor the treatment o f dye-bearing effluents. In this study, different agro-wastes were screened as adsorbent for the removal of selected reactive dyeT blue G from aqueous solution. The effects o f various experimental parameters like time, temperature, pH and adsorbent dose on decolorization was investigated and optimal conditions were determined for decolorization in batch mode. Among the different agro-wastes screened, maximum decolorization was achieved with wheat bran. Maximum decolorization capacity was found to be with two per cent of adsorbent concentration and pH7 was found to be favorable for decolorization of T. Blue Greactive dye. An incubation time of 30 h at 50*^C wiis found to be optimum for dye decolorization. Waste water reuse is a favorable alternative which can reduce pollution and add-on the available water resource. In the present study, the decolorized solution was reused for dyeing cotton fabric. It is found that the physical and color fastness properties of the fabric dyed with decolorized water was comparable with that of the fabric dyed using fresh water. The results indicate that the selected agro-waste wheat bran could be employed as low-cost adsorbent for the removal of reactive dye T.Blue Gfrorn dye waste water.
