THE USE OF AGRICULTURAL WASTE AS ADSORBENTS FOR THE TREATMENT OF WASTEWATER FROM DICLOPHENAC
The article presents the results of studies on obtaining adsorbents from pomegranate peels and date seeds for their further use as adsorbents for the removal of drugs from wastewater. The results of obtaining target sorbents with the use of an additional activator - phosphoric acid are given. It has been shown that modified (treated with phosphoric acid) pomegranate peel shows adsorptive activity in removal of nonsteroidal anti-inflammatory drug diclofenac, from aqueous solution. A comparative study showed that the sample treated with phosphoric acid shows higher adsorption capacity compared to the unmodified counterpart. And the adsorption capacity of AU obtained from date seed is the highest. The economic and technical feasibility of using such sorbents in practice is established. The data about equilibrium are interpreted by the model of Langmuir isotherm.Sorption activity was established by comparison of the received results with theoretical provisions of the Langmuir theory.
