Abstract:
Magnetic magnetite (Fe 3 O 4 ) nanoparticles with average sizes of 5.11, 10.53, and 14.76 nm were synthesized by the chemical co-precipitation method. The surface area of Fe 3 O 4 nanoparticles (average size of 5.11 nm) had the largest value of 167
m 2 /g. The adsorption capacity for removing arsenic (As(V)) from water at 3 ppm concentration was investigated by atomic absorption spectroscopy. Results showed that the As(V) adsorption capacity of Fe 3 O 4 was dependent on particle size. The maximum absorption
efficiency ( H max ) reached 99.02%, the equilibrium time was 30 min; the maximum Langmuir isotherm adsorption capacity was 14.46 mg/g with Fe 3 O 4 nanoparticle an average size of 5 nm. The results indicate that reducing the size of Fe 3 O 4 nanoparticles is a promised way for As(V) ion removal from water and wastewater treatment.
