Abstract: Heavy metals from mining, smelting operations and other industrial processing facilities pollute the environmentit was timedependent. Capacity experiments demonstrated that at pH 2, esterified hops biomass bound 33.4 mg Au g ofbiomass, while native and hydrolyzed hops biomasses bound 28.2 and 12.0 mg Au g of biomass,respectively. However, at pH 5 the binding capacities were 38.9, 37.8 and 11.4 mg of Au per gram of native,esterified and hydrolyzed hops biomasses, respectively.
