Application of impregnated biocarbon produced from soybean hulls in dye decolorization
Waste soybean hulls (WSH) were investigated as a Fe-support in two forms: raw and carbonized (i.e. biocarbon, BC), as possible value-added materials. Fe-impregnation was implemented in order to produce heterogeneous Fenton catalysts for Reactive Blue 4 dye degradation. Materials characterization dem...
