چکیده
|
The analyses of optimization,modeling,equilibrium and kinetics of catechol removal on multiwall carbon nanotube (mwcnt) have been studied. the optimization process was performed using response surface methodology (rsm). the optimum amount conditions were ph 4.5,initial catechol concentration 87 mg/l,mwcnts 237 mg and contact time 22 min. under this condition,the optimum adsorption percentage of catechol was obtained about 90. the kinetic and isotherm studies on the obtained optimum condition represented that the pseudo-first order and freundlich equilibrium are more fitted with experimental data than other models.
