Extraction of nickel ions using nanoporous adsorbent material from waste glass

Abstract

This study aims to create a porous glass adsorbent from waste glass to extraction nickel ions from its aqueous solution. The process involves converting waste glass to porous glass using 1:1:1:1 lime, sodium chloride, and sodium bicarbonate, followed by reacting with waste glass at 800 ˚C. The porous glass surface morphology, elemental composition, and functional groups, were analyzed using SEM, EDS, and FT-IR techniques.The outcome parameters used in this study are adsorbent dosage (10 g), contact time (150 min), heavy metal ion concentration (100 mg/l), and pH of 6. The adsorption capacity resulting from these parameters is 9.28 mg/g using the porous extract adsorbent for the extraction of nickel ions from its solutions. According to the findings. The proportion of Ni (II) ions extracted increased, coupled with a rise in the adsorbent dosage, heavy metal ion concentration, contact time, and pH. In addition, the Langmuir isotherm (R² = 0.98,K_L=0.072) has shown better performance than the Freundlich adsorption isotherm (R² = 0.93,N=1.598) for the adsorption of the Ni(II) in this study.
