Adsorption Characteristics of Hg2+ Ions Using Fe3O4/Chitosan Magnetic Nanoparticles

Abstract:

Article Preview

Fe3O4/chitosan magnetic nanoparticles were prepared by chemical cross-linking technique, using dialdehyde starch as a crosslinker, and the adsorption performance of the adsorbent toward Hg2+ was investigated. The adsorption capacity of mercury ions was greatly affected by pH value, adsorption doses and adsorption time. Results indicated that optimal adsorption conditions were pH value, 6, adsorption doses, 140 mg.L-1, adsorption time, 20 min, and the adsorption capacity was 25.12 mg.g-1. The well-defined nanoparticles with a uniform distribution were observed.
