Removal of Iron, Manganese, Cadmium, and Nickel Ions Using Brewers’ Spent Grain

The human-made pollution of surface and ground waters is becoming an inevitable persistently urgent problem for humankind life in general, as these pollutants are also distributed by their natural circulation. For example, from mining activities metallurgy, toxic heavy metals pollute the environment present material risk human health environment. Bioadsorbers intriguing way to efficiently capture eliminate hazards, they environmentally friendly, cheap, abundant, efficient. In this study, we brewers’ spent grain (BSG) efficient adsorber metal ions, based on examples iron, manganese, cadmium, nickel ions. We uncover adsorption properties two different BSGs investigate thoroughly chemical physical well efficiency adsorbers simulated real waters. As a result, found that behavior BSG types differs despite almost identical chemistry. Elemental mapping reveals all components contribute adsorption. Further, both not only able purify water reach acceptable levels cleanness, but yield outstanding performance iron ions 0.2 mmol/g 0.1 mmol/g.
