Comparison of Non-Linear and Linear Ho Models Applied for Copper Ions Sorption on Geopolymer

The Ho pseudo-second-order model is the best fitting model in describing the sorption of copper ions on synthesized geopolymer for the selected experimental conditions (particle size 0.071–0.090 mm at agitation speed of 240 rpm). For that reason, a comparison of one non-linear and five linear forms...
