Adsorption and decolorization of dyes using solid residues from Pleurotus ostreatus mushroom production
We investigated the use of solid residues from Pleurotus ostreatus mushroom production in adsorbing and decolorizing different dyes. The solid residue used in this study was composed of hemicellulose and cellulose (52.81 %), acid-insoluble lignin (25.42%), chitin (6.5%), and water extractives (14.82...
