Abstract

The aim of this study to synthesize NANOPARTICLE zero valent IRON and to determine its efficiency in ARSENIC removal from AQUEOUS SOLUTIONs NANOPARTICLEs were synthesized by reduction of ferric chloride using sodium borohydrid. The experiments were conducted in a batch system and the effects of pH, contact time, and the concentrations of arsenit, arsenat, and nano zero valent IRON were investigated. SEM and XRD were applied for the determination of particle size and characterization of the NANOPARTICLEs synthesized. SEM results revealed that synthesized particles were of nano size (1-100 nanometers). At pH=7.0, 99% of arsenit and arsenat was removed when nano zero valent IRON concentration was 1 (g L-1) over a retention time of 10 min. Based on the results obtained, the removal efficiency was enhanced with increasing nano zero valent IRON dosage and reaction time, but decreased with increasing initial concentration and initial solution pH. The significant removal efficiency, high rate of process and short reaction time showed that IRON nano particles are of a significant potential for the removal of ARSENIC from AQUEOUS SOLUTIONs.
