|dc.description.abstract||Chromium is an important industrial metal used in various production processes. Remediation of Chromium contaminated sites present both technological and economic challenges, as conventional methods are often too expensive and difficult to operate. Green synthesis provides advancement over chemical and physical method as it is cost effective, environment friendly, easily scaled up for large scale synthesis. In this study, bamboo supported Zero-valent iron (Fe0) nanoparticles were synthesized, characterized, and were tested for adsorption of Cr (VI). Fe0 nanoparticles were synthesized by the reduction of ferric chloride with avocado seed extract polyphenol and were characterized by UV–Visible spectro- photometer, FTIR (Fourier transform infrared) spectroscopy and XRD (X-ray diffraction). Batch experiments were performed using various concentrations of Fe0 nanoparticles for reduction of Cr (VI). The synthesized nZVIbamboo was subsequently applied to the adsorption of hexavalent chromium from aqueous solution. The adsorption of chromium was investigated under various experimental conditions such as pH, initial concentration of chromium and adsorbent dosage. The results showed that the synthesized nZVI-AB adsorbent was able to perform the maximum adsorption capacity of 18.913 mg/g. and at a concentration of 20 mg/L, pH of 3 and 1 g of nZVI bamboo adsorbent concentration which resulted in 92.38% and optimum removal percentage. The equilibrium data was best represented by Langmuir isotherm.||en_US|
