Abstract

In this study, response surface methodology was used to study the optimization of bleaching of palm oil using local clay from Enugu State of Nigeria. The clay was subjected to acid activation using HNO3 and H2SO4 as activating agents. The interaction effects of the process variables on bleaching performance of Palm Oil by activated clay samples were investigated using Design Expert Software. The experimental results of adsorption process showed that all the linear effects of independent variables of dosage, time and temperature investigated were highly significant as well as their interactive effects. The optimum conditions for the maximum adsorption efficiency of 84.13% and 86.25% for the two clay samples were obtained at temperature of 500C, clay dosage of 3.0g and time of 30 minutes. The model predicted R2 is in a reasonable agreement with the adjusted value while a high determination coefficient of greater than 98% was recorded. This study shows that Eha-Ndiagu clay is a classified highly rated adsorbent whose adsorptive potentials can be maximized under optimum process conditions.
