摘要:	The adsorption of benzothiophene sulfone and dibenzothiophene sulfone from diesel using six different types of adsorbents were investigated. Adsorbents used were commercial adsorbents granular-activated carbon (GAC), aluminum oxide (ALU), novel adsorbents chitosan-coated bentonite (CHB), and metal-ion impregnated activated carbons, where there types of metal ions, Cu2+, Fe3+, and Ni2+, were loaded (Cu2+/AC, Fe3+/AC, Ni2+/AC). Kinetic studies conducted showed that the adsorption process followed a pseudo-second-order kinetics. Equilibrium studies indicated that the heterogeneous and homogenous monolayer adsorption and are present in the process. Moreover, based on the results of sulfone removal using the synthetic diesel fuel, increasing removal efficiencies of Benzothiophene sulfone followed the order of ALU<GAC<Cu2+/AC < <Fe3+/AC<CHB, while for dibenzothiophene sulfone (DBTO) removal, increasing DBTO removed efficiencies followed the order of GAC<CHB<ALU<Cu2+/AC approximate to Fe3+/AC approximate to Ni2+/AC.
