Investigation of Adsorption Properties of Some Pesticide Species with Chitosan

In this study, the removal of certain insecticides and herbicides from aqueous solutions using the adsorption method was aimed. For this purpose, chitosan was used. Chitosan was treated with insecticide and herbicide solutions, and the effects of contact time and changes in insecticide and herbicide concentrations on adsorption were separately examined. The applicability of the Langmuir adsorption isotherm was tested at 25°C. Quantitative analyses were performed based on the initial amount of the substance added to the water and the remaining amount in the solution. The quantifications were carried out using a GC-MS device. Based on the plotted graphs, it was demonstrated that chitosan can be used as an adsorbent.
