Abstract
Adsorption 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.
