Abstract EN
The adsorption isotherms for Cu2+ and Ni2+ onto Tripoli were investigated in this study.
It is found that adsorption follows the Langmuir model for both ions.
The free energy of adsorption (ΔG) of Cu2+ adsorption was found to be -19.74 (± 0.83) kJ/mole and that of Ni2+ was -21.47 (± 2.4) kJ/mole.
The affinity of Tripoli towards both ions is found to be the same as these values of free energy of adsorption for both ions are statistically similar as predicted from the student’s t-test.
The rate of adsorption of nickel ion is found to be higher than that of copper ion as shown from the concentration versus time plots for both ions.
The maximum adsorption capacities for Cu2+and Ni2+ were found to be 4.5(±0.4)x10-5 mol/g and 10.2(±0.5)x10-5 mol/g, respectively.
These two values are statistically different as found from the student’s t-test at 95% confidence level.
The pH values for all solutions were in the range of 4 to 5.
