For their unique physical, chemical and biological characteristics, silver nanoparticles (AgNPs) are used in a variety of applications in the sectors of health and wellness as well as consumer and industrial products. We describe here the production of silver nanoparticles (AgNPs) using activated carbon from locally accessible biowaste Caesalpinia pulcherrima pod is the goal of this work, which aims to characterise the activated carbons generated by oxidation of activated carbons of comparable porosity with Sulphuric acid, nitric acid, and phosphoric acid, respectively. Using Caesalpinia pulcherrima plant extract as a reducing agent, silver particles may be made. TEM was used to determine the particle size, distribution, shape, shape heterogeneity, and aggregation. Analysis of the silver nanoparticle's composition has been done using EDAX. According to the findings, activated carbon derived from Caesalpinia pulcherrima pod is ideal for the adsorption of textile dyes such as Eriofast Blue (EB) and Erionyl Orange (EO) and might be employed as a low-cost efficient adsorbent in the treatment of industrial wastewater.
