Description
Summary:AbstractIn this paper, amine-functionalized magnetic ferrite nanoparticle (AMFN) was synthesized. Dye removal ability of AMFN and magnetic ferrite nanoparticle (MFN) was investigated. Physical characteristics of AMFN were studied using Fourier transform infrared (FTIR) and scanning electron microscopy (SEM). Direct Red 31 (DR31), Acid Blue 25 (AB25), and Acid Red 14 (AR14) were used as model compounds. The kinetic and isotherm of dye adsorption were studied. The effects of operational parameter such as adsorbent dosage, pH and salt were evaluated. Adsorption kinetic of dyes was found to conform to pseudo second order kinetics. The maximum dye adsorption capacity (Q0) was 0.271  mg/g DR31, 0.756  mg/g AB25 and 0.581  mg/g AR14 for MFN and 185.185  mg/g DR31, 161.290  mg/g AB25 and 147.059  mg/g AR14 for AMFN. It was found that dye adsorption onto MFN and AMFN followed Langmuir isotherm. The results showed that the AMFN being a magnetic adsorbent with high dye adsorption capacity might be a suitable alternative to remove dyes from colored wastewater.
