Abstract

Mono, di and tri valent cationic soap of two oils (shear butter; Butryspermum Parkii and rubber seeds; Hevea Brasiliensis) labeled as Mx- Y soaps were used as adsorbates for the adsorption studies. Initial adsorbates concentration ranged from Co values of 0.20 to 3.0mmol/L which after equilibration, corresponds to various attained equilibrium concentrations that depends on the metallic soap uptake under investigation at a fixed temperature of 27°C. Generated data were treated with five isotherm models, namely Langmuir, Freundlich, Temkin, BET and Dubinin Radushkevich isotherms. Applicability test via its coefficient was adopted in explaining the best fit isotherm. Sorption capacity (qe,qm,qs), intensity (k), surface coverage (n, RL), binding affinity characteristics [KF (L/g), Ka (g/mmol), A,b (L/mmol), CBET (L/g)] as well as the energy parameter constants BD and E (KJ/mmol) deduced from the isotherms were all used in measuring the sorption phenomenon and performance of derived home based metallic ore (hematite; α-Fe2O3). Equilibrium conditions were attained using sets of batch reactors for experimental runs. The sorption performance of metallic soaps uptake varied according to the nature of metallic soaps, difference in surface ions and ionic charge concentrations of each adsorbate.
