The adsorptive property of acid fuchsin on magnetic carbon nanotubes was studied.The effects of adsorbent dosage,adsorption time,initial dye concentration,temperature and pH on the adsorption efficiency were investigated.Adsorption kinetics and adsorption isotherm were researched.The resultant kinetic data were well fitted by apseudo-second-order model,the correlation coefficient R2 was 0.99.The adsorption isotherms for acid fuchsin could be suitably described by the Langmiur isotherm model and D-R isotherm...
