Residues from pharmaceutical products are found in effluents and in other environmental matrices such as soil and surface waters. Chitin and chitosan are highly adsorptive substances present in mushrooms such as champignon (Agaricus bisporus) and shiitake (Lentinula edodes). This study evaluated the adsorption efficiency of shiitake and champignon stalks, and shiitake substrate in water contaminated with paracetamol and 17 α-ethynyl estradiol (EE2). Stalks and substrate were dried and ground. Particles were physically evaluated and chemically characterized. Adsorption kinetic and isotherms were carried out for EE2 and paracetamol. Shiitake and champignon stalks had high percentage of porosity, closed and open pores. All bioproducts from mushroom had chemical groups similar to chitosan standard. However, the degree of deacetylation of chitosan was higher in shiitake (28.3%). In EE2 adsorption kinetics, shiitake and champignon stalks showed 100% removal in 20 and 30 min, respectively. Shiitake substrate showed 80% removal. In paracetamol adsorption kinetics, all bioproducts presented more than 95% removal. In EE2 adsorption isotherm, the maximum adsorption capacities (qmax) to shiitake and champignon stalks and shiitake substrate were 5.62, 18.95 and 0.31 mgEE2/g, respectively. For paracetamol adsorption isotherm, qmax to shiitake and champignon stalks were 34.20 and 338.08 mgparacetamol/g, respectively. In conclusion, shiitake and champignon stalks (specially champignon) had the best results regarding the adsorption of EE2 and paracetamol. Reuse of discarded mushroom waste reduces the environmental impact and can add value to the product.
