ABSTRACT: This review focused on the isotherm modeling of the removal of lead and metallic contaminants from pharmaceutical wastewater using activated oil palm empty fruit bunch. The heavy metals in pharmaceutical wastewater sample were revealed by the Atomic Absorption Spectrometry analysis, which proved that lead and cadmium metals are the most dangerous metals in the sample under analysis because they exceed the acceptable limitsgiven by World Health Organization. The nutritional value of the raw and activated oil palm bunch, revealed through proximate analysis, indicated an increase in adsorbent properties after chemical activation. The surface morphological analysis of the raw and activated samples revealed considerable increment in the number of the vacant pores for effective adsorption after acid treatment while the Fourier Transform Infrared Spectrometer analysis also indicated an increase in void spaces after activation due to the disappearance of certain functional groups. Kinetic, thermodynamic and isotherm modelling of lead and cadmium removal by adsorption were done using standard equations. Langmuir model closely followed by Temkin model were the most fitting models for the adsorption experiment. Pseudo-second order kinetic model is the most suitable kinetic model while the results from the thermodynamic analysis, such as change in enthalpy, change in entropy and standard Gibb’s free energy showed that the process is notspontaneous. The adsorption was carried out in batches to determine the effects of stirring time, temperature and dosage of the activated palm bunch on the removal of lead and cadmium ions.These process conditions were optimized with central composite design of response surface methodology with the aid of a design expert (version 13). The response was removal efficiency while the suggested model was quadratic. The predicted adsorbent removal efficiencies for lead and cadmium are 89.234% and 73.318% respectively at 69.150mins, 345.155°C and 0.266g adsorbent dosage. This was validated by carrying out the metal removal at the suggested conditions to obtain actual adsorbent removal efficiencies of87.82% and 72.51% for lead and cadmium respectively.Thus, activated oil palm bunch is economically viable and practically proven biomass waste for pharmaceutical wastewater treatment.
