Adsorption of antibiotics using powdered, granular, and coffee bean activated carbon

Adsorption isotherm and kinetics of antibiotics using activated carbon are commonly researched but a comparison of adsorption powdered activated carbon (PAC), granular activated carbon (GAC), and powdered coffee bean activated carbon (CBAC) was not adequately evaluated. In this study, adsorption iso...

description Adsorption isotherm and kinetics of antibiotics using activated carbon are commonly researched but a comparison of adsorption powdered activated carbon (PAC), granular activated carbon (GAC), and powdered coffee bean activated carbon (CBAC) was not adequately evaluated.
