Abstract

The discovery of various advanced materials that are applicable in remediation of environment pollutants was rapidly advancing because of their applications in wide range. Green synthesized Nano particles (NPs) were currently gaining attention in photodegradation of dyes and metals due to its ecofriendly, cost effective and simple production. Hence this study intended to synthesize and characterize the nano sized copper particles using aqueous root extract of Schrebera swietenioides Roxb., as green reducing agent. The synthesized NPs were characterized and proved that the NPs were aggregates with spherical shape to undefined shapes with an average particle size of 32±4 nm and contain 82.5 % of copper metal in the particles. Further, the synthesized NPs were applied for the removal of Sudan red (III) dye, Azure A dye and Lead metal. The findings proved that the NPs had potential degradation efficacy on the degradation of Sudan dye, Azure A dye and Lead metal. The NPs were durable and could be reusable with high degradation efficacy after three cycles of study for both dyes and metal in the study. Therefore, the green synthesized Cu NPs are potential candidates for photocatalytic applications. Keywords: Copper nano particles, Photo catalytic activity, Azure A dye, Lead metal degradation.
