Abstract

Isotherm and kinetic properties of formaldehyde adsorption on oil palm fibre-TiO2 composite powder; a gas-solid system was studied. Oil palm fibre-TiO2 composite powder was prepared by mixing oil palm fibre with TiO2 powder with ratio of 4:1 using a mechanical milling technique. The test was done in a test chamber where oil palm fibre-TiO2 composite powder was left to passively adsorb the formaldehyde. The maximum adsorption capacity value and kinetic properties depends on initial concentration of formaldehyde. Formaldehyde initial concentration of 2.1 and 0.5 ppm was best presented by pseudo-first order and pseudo-second order, respectively, while for initial concentration of 0.75 and 0.9 ppm, both were well presented by Elovich model. The adsorption isotherm of formaldehyde was best described by Freundlich isotherm which showed the highest correlation coefficient, R2 = 0.9397 compared to Langmuirs' (R2 = 0.8692) and Temkins' (R2 = 0.8756) correlation coefficients. Equilibrium parameter of 0>RL>1 which showed the formaldehyde adsorption onto oil palm fibre-TiO2 composite was favorable to happen.
