Development of environment-friendly magnetic nanobiocomposites and full factorial design (FFD) analysis for strontium removal from aqueous solutions

Abstract

In this study, magnetic (Fe3O4) nanobiocomposite were synthesized by a co-precipitation method using pectin biopolymer as a stabilizer. Nanobiocomposites were characterized via several characterization methods. The particle size and surface area of the nanobiocomposite were found as 5.76 nm 94.651 m2/g, respectively. The TEM and SEM results indicated that the spherical nanoparticles were well dispersed into the polymer matrix. Optimal adsorption parameters were determined using FFD. It was determined that pH and initial concentration are the main effects on the Sr(II) removal. Maximum sorption capacities according to D–R and Langmuir isotherms were determined as 0.018 mol/g and 26.455 mg/g, respectively.
