  • Water dependency of energy generation systems generate polluted water. Efforts are required to purify energy-related wastewaters. Here in, eight keratin-based sorbents (KBPs) from chicken feathers were developed, characterized for their physicochemical properties, and then tested against nine trace metals (at 100 μg L−1 each) from multi-metal synthetic water simulating wastewater from energy industry. Among the eight biopolymers, KBP-I removed 87–93% of AsIII, Cd2+, KBP-IV adsorbed 80–91% of Cu2+, VV, CrVI, and KBP-V removed 60–90% of Co2+, Ni2+, Zn2+. Based on these initial results, adsorption performances of KBP-I, KBP-IV and KBP-V were further evaluated under a range of environmental factors (pH, temperature, contact time). At last, the hybrid sorbent (KBP-IX) was developed by mixing the KBP-IV and KBP-V at various ratios to analyze their synergistic affect for targeting higher removal efficiencies.
