САЖЕТАК / ABSTRACT:
The widespread use of the organophosphate pesticide chlorpyrifos, coupled with its acute neurotoxicity, underscores the urgent need for effective remediation strategies. Among the various methods explored for chlorpyrifos removal from water, adsorption has emerged as the most promising. We investigated the potential of two cellulose-derived porous carbons, produced via different activation strategies, as adsorbents for chlorpyrifos removal from water. The kinetics of batch adsorption fit well with both pseudo-first-order and pseudo-second-order models for both materials. Additionally, the Freundlich and Langmuir isotherm models accurately described the adsorption process in all cases studied. The maximum adsorption capacities, determined from the Langmuir model, were 3.8×106 mg g−1 and 1.3×106 mg g−1. Comparative analysis with existing literature validates these findings, highlighting the efficacy and potential of cellulose-based porous carbons for sustainable chlorpyrifos remediation.
