摘要:
Batch experiments were carried out to study the adsorption characteristics of Cu(II) onto Carboxymethylcellulose Sulfate(CMC-S). Previous studies had shown that Acidic/neutral pH was favorable to the adsorption of Cu(II). The Kinetic and thermodynamic analysis were performed in detail. Kinetic studies indicated that Cu(II) adsorption on CMC-S in the system followed the pseudo-second order kinetics. Moreover, the experimental equilibrium data was analyzed using the linearized form of Langmuir, and the Langmuir isotherm was found to provide the best theoretical correlation of the experimental data for the adsorption of Cu(II). The monolayer adsorption capacity was determined to be 127 mg of Cu(II) per gram of CMC-S at 25 degrees C. Thermodynamic analysis showed that adsorption process obeys an exothermic path of the negative value of Delta H degrees and spontaneous with negative value of Delta G degrees.
