Physical and chemical methods have been used to synthesize zerovalent iron nanoparticles (nZVI) for the treatment of industrial effluents and contaminated water. However, the major limitations of these methods include usage of toxic chemicals such as NaBH4 and high energy consumption. Therefore, alternative green synthesis route for nZVI based on eco-friendly; low-cost; bio-based and nonhazardous methods are required. In this work, nZVI were synthesized from green tea extract (camellia sinensis) and supported on kaolin for natural organic matter (NOM) sequestration from aqueous media by degradation and adsorption. Further, opportunities for Fenton regenerative valorization of spent media were investigated. The research focused on the effect of initial concentration (1 – 25 mg/L), adsorbent dose (0.1–0.9 g), contact time (0 – 180 min) and pH (2 – 9) by batch experiments. The R2 for Langmuir and Freundlich models were comparable (0.975 and 0.977, respectively) meaning the isotherm data could be best described by either of these models. The calculated Qe value (0.1525 mg/g) using the pseudo-second-order model was closer to the experimental values Qe value (0.1382 mg/g). This indicated that the kinetics was delineated better by a pseudo second- order model. While operating at optimal conditions of pH (4.5) and H2O2 dosage (5 mM), no significant reduction in the adsorption capacity of K-nZVI was observed even after four successive adsorption-regeneration cycles. From the results of the study it was established that biosynthesis of nZVI and supporting it on kaolin can serve as a safe, economic and effective natural adsorbent for NOM removal from aqueous media.
