Heavy metal sorption in biosorbents – Using spent grain from the brewing industry
2019
The sorption properties of brewer's spent grain (BSG) were assessed in terms of its usefulness in removing heavy metals from solutions. The specific objectives of the investigation involved studying sorption equilibrium and kinetics, assessing the influence of other cations on sorption efficiency, and examining the possibility of bed regeneration. The studies were carried out in a static system, with a constant ratio of solution volume to biosorbent mass, and using a flow through system. The affinity of metal cations to BSG functional groups was established and increased in the series: Mn2þzZn2þ < Ni2þ < Cd2þ < Cu2þ < Pb2þ. The BSG's sorption capacities (mmol g�1), determined using the Lang…
