Studies on desorption of individual textile dyes and a synthetic dye effluent from dye-adsorbed agricultural residues using solvents.
Two solvents, A and B (A: methanol, chloroform, water in the ratio 1:1:1; B: 50% methanol), were used to extract textile dyes adsorbed onto substrates for the purpose of future analyses of the amount of dyes degraded through solid state fermentation (SSF) using white rot fungi. Barley husk, apple pommace and corncob were separately soaked in five different dye solutions and a synthetic textile effluent. A maximum value of 93% desorption of Cibacron Red from corncob was achieved using solvent A. Barley husk was the only substrate from which the synthetic textile effluent could be desorbed, with 82% being recovered using solvent A.
