Abstract

Arsenic (III) was treated by newly synthesized ferric oxide nano composite supported on amino resin (NXHFO). Amberlite XAD-4 was converted to amino derivative (NX) and HFO particles were prepared on its surface. Batch study was conducted to study the removal of arsenic from aqueous media. Uptake of similar to 98.5% was recorded at pH 4 using 50 mg of NXHFO while the agitation time was 30 min. Monolayer sorption capacity of NXHFO resin calculated from Langmuir sorption isotherm for As(III) ions was 32.3 mg g(-1). The sorption energy (E) calculated was 15 kJ mol(-1), suggesting that the uptake of arsenite onto the NXHFO surface was due to ion-exchange.
