Green Synthesis of Nickel Nanoparticles using Fruit Peels of Citrus Paradise for Remediation of Congo Red Dye

Abstract

Abstract. Biosorption is a cost-effective excellent tool for removing problematic dyes. The present work was focused on the utilization of Citrus paradise (grapefruit) peels aqueous extract for synthesis of nickel nanoparticles. The prepared nanoparticles were characterized by SEM and were used for the remediation of congo red direct dye. The decolorization of Congo Red direct dye was measured using UV/Visible spectrophotometer following the optimization of experimental factors. Maximum decolorization was observed at a dye concentration of 0.02 %, pH 6, at 50 °C temperature, and catalyst dose was 0.01 g/L. TOC and COD values were found to be 79.89 % and 78.23 %. Agriculrural waste could be used for the remediation of other synthetic dyes as well; hence helps in cleaning our natural environment.
 
 Resumen. La biosorción es una excelente herramienta rentable para eliminar colorantes problemáticos. El presente trabajo se centró en la utilización del extracto de cáscaras de Citrus paradise (pomelo) para la síntesis de nanopartículas de níquel. Las nanopartículas preparadas se caracterizaron por microscopía electrónica de barrido (MEB) y se utilizaron para la remediación del colorante directo rojo de Congo. La decoloración del colorante directo Rojo Congo se midió mediante espectrometría siguiendo la optimización de factores experimentales. Se observó una decoloración máxima a una concentración de colorante de 0.02 %, pH 6, y una temperatura de 50 °C; la dosis del catalizador fue de 0.01 g/L. Se determinó que los valores de TOC y DQO eran 79.89 % y 78.23 %, respectivamente. Los residuos agrícolas también podrían utilizarse para la remediación de otros tintes sintéticos y con ello ayudar a limpiar nuestro entorno natural.

Green Synthesis of Nickel Nanoparticles using Plant Extract

“…Many studies have proved the high stability and non-toxicity of metal nanoparticles obtained by green synthesis, such as [5][6][7][8][9]. Many works are devoted to the production of nickel nanoparticles by green synthesis using various biological sources, for example plants Aloe vera leaves extract [10], leaf extract of Coriander [11], Peumus boldus extract [12], Citrus paradise (grapefruit) peels [13] and others.…”
