Synthetic dyes are made of carcinogenic and mutagenic compounds and used in textile, paper and printing industries. Reactive Black 5 (RB5) and Remazol Brilliant Blue R (RBBR) are known to cause asthma and allergic dermatitis. Thus dye decolorization from industrial wastewaters is of utmost importance. Conventional methods viz. adsorption, flocculation, coagulation, oxidation and reverse osmosis are usually inefficient, expensive, of limited applicability which are difficult to dispose off. In the present study, the potentiality of dead macrofungi Pleurotus platypus (oyster mushroom) and Agaricus bisporus (button mushroom) for dye removal was investigated. The effect of different parameters viz. pH, temperature, biosorbent dosage and initial dye concentration on dye removal was investigated. Application of dried macrofungi as adsorbents can be an effective method for the removal of Reactive Black 5 (RB5) and Remazol Brilliant Blue R (RBBR) from dye bearing wastewater.
