Abstract

The adsorption of roxithromycin from aqueous solution onto multied-walled carbon nanotubes was studied. The gravimetric method can be adopted for calculating the adsorption isotherm and kinetic curves of roxithromycin onto the carbon nanotubes. The influential factors including the pH and humic acid on the adsorption efficiency were investigated in the paper. Experimental results indicated that the adsorption kinetics and isotherm can be well described by using a pseudo-second-order rate model and Freundlich isotherm, respectively. The adsorption capacity of roxithromycin decreased with the addition of erythromycin in water. The adsorption capacity of roxithromycin decreased when the pH was less 4 while adsorption capacity increased when the pH more than 4．The promotion action of the adsorption of roxithromycin onto multi-walled carbon nanotubes happened when the concentration of humic acids was less 25mg/L while the inhibition action happened when the concentration of humic acids was more than 25mg/L.
