Abstract
Abstract Corncob waste can be utilized for various purposes. The purpose of this research is to determine corncob adsorption ability and adsorption kinetics model of purified used cooking oil using natural and activated corncobs which is effective and economical method due to its low cost, simple, and regenerative. The research method used in this research is experimental. This study consisted of three stages, namely the manufacture adsorbent of natural and activated corncobs, purification, determination turbidy of used cooking oil. The natural corncob adsorbent turbidity is 13.2 NTU and the activated corncob adsorbent turbidity is 10.8 NTU. Percentage removal efficiency of natural corncob adsorbent is 97.238% and activated corncob adsorbent is 97.741%. It is shown from the pseudo-second-order graph that a chemical interaction occurs, the value of the coefficient of determination (R2) obtained is 1, using natural and activated corncob adsorbent.
