Agricultural Waste-Based Alternative Adsorbents for the Remediation of Organophosphate Pesticide from Water
Abstract
The study focuses on using agricultural waste-based alternative adsorbents for the remediation of organophosphate pesticide-profenofos from water. Date pits agricultural wastes were used to prepare three types of adsorbents, namely roasted date pits (RODP), activated date pits (ACDP) and nano-activated date pits (NACDP). To determine the efficiency of these adsorbents to treat wastewater, different physical and chemical characterizations were studied, such as scanning electron microscopy (SEM) and BET surface area. Adsorption isotherms models were examined in order to understand the interactions between the adsorbate profenofos and the prepared adsorbents. In addition, thermodynamic adsorption was carried out to determine the homogeneity and spontaneous of the adsorbents.
