Abstract

Nitrite Adsorption from Aqueous Solutions Using Amberlite IRA-67

Author(s): Rima Drissi, Chaabane Mouats

Adsorption of nitrite ions in aqueous solution onto anion exchange resin Amberlite IRA-67 has been studied. The influence of different operating parameters was evaluated in batch experiment including resin dosage, contact time and initial concentration. Adsorption followed pseudo second order kinetics model with maximum nitrite removal capacity of 16.23 mg/g. Experimental data could be well fitted using Langmuir isotherm with correlation coefficients above 0.99. Scanning Electron Microscopy (SEM) and Fourier-transform Infrared Spectra (FT-IR) were employed to characterize the resin
