Synthesis and Modification of Neem Leaf (Azadirachta indica) with Nimbidin: Biosorption Application

Authors: Nene Pearl Eluchie

Abstract:

Globally, metal ion, particularly those generated from oil and gas effluents, form environmental pollution, particularly in developing regions like Nigeria, where water borne disease is fatal. This is clear evidence for metal ion contamination within the environment. Ecofriendly and cost-effective biomaterials are the best ways of reducing metal ion contamination, thus reducing the need for chemical treatment of oil and gas effluent. Despite this, research efforts to understand the mechanism of adsorption and possible biosorptive remediation interventions are limited. The study employed nano adsorption techniques such as UV-Visible spectroscopy, SEM, FTIR in a progressive manner to provide insight. The biosorption efficiency of A. indicasilver nanoparticle (AI-AgNPs) was within the range of 63-95%. The study demonstrates that AI-AgNPs can be a promising agent, cheap, efficient, and biodegradable adsorbent for lowering oil and gas contaminants. This is one of the few studies showing that A. indica is one of the many biomaterials that can be used to synthesize silver nanoparticles through the reduction of active constituents (such as Nimbidin) present in them to ensure stability and surface properties, which are critical for their performance in effluent treatment. Therefore, leveraging the knowledge from this study to raise awareness through public health initiatives and community engagement will help. The prevalence of metal ions observed in the visible region in the study indicates the need for biosorption approaches, not only in social settings but also in the immediate environment. There is, thus, an urgent need for targeted interventions in vulnerable communities.
