Abstract
Pesticides are highly hazardous chemicals for the environment and human health and their use in agriculture is constantly
increasing. Although 1,1,1-trichloro-2,2-bis(4-chlorophenyl) ethane 4,4′-DDT was banned at developed countries, it is still
one of the most dangerous of chemical due to accumulation in the environment. It is known that the toxicity of DDT affects
some enzyme systems biochemically. The main motivation of this study is to develop an effective adsorbate for the removal DDT,
which was chosen as a model hydrophobic pesticide, out of aqueous systems. For this purpose, the bare diatomite particles were
magnetically modified and a hydrophobic ligand attached to enhance its adsorptive and physio-chemical features. Under optimal
conditions, a high adsorption capacity, around 120 mg/g with the hydrophobic and magnetic diatomite particles, modification of
the diatomite particles reduced average pores diameter whereas surface area and total pore volume increased (around 15-folds).
After five consecutive adsorption–desorption cycles, no significant decrease in adsorption capability was observed. The adsorption isotherms (Langmuir, Freundlich, and Flory–Huggins) applied to the data indicated that the adsorption process occurred via
monolayer adsorption in an entropy-driven manner. The kinetic data also revealed the quick adsorption process without any
diffusion limitations
