A comparative study of adsorption behavior of rifampicin, streptomycin, and ibuprofen contaminants from aqueous solutions onto chitosan: Dynamic interactions, kinetics, diffusions, and mechanisms

Adsorptive removal and dynamic interaction of three different pharmaceutical pollutants, namely rifampicin (RIF), streptomycin (STM), and ibuprofen (IBU) onto chitosan were systematically investigated using a batch adsorption technique at different processing parameters. In this study, chitosan was...
