Abstract

Fatty hydroxamic acid (FHA) immobilized in polymethylmethacrylate (PMMA) has been studied as a sensor for V(V). Based on this sensing material, the response towards the different concentration of V(V) was found to be linear in the logarithmic concentration range of 0-2.3 (i.e. 1.0-200 mg L -1). The detection limit was 0.7 mg L -1. The relative standard deviation (R.S.D.) of reproducibility was 9.3 and 7.1% for V(V) at concentration of 50 and 200 mg L -1, respectively. Interference from foreign ions was also studied at a molar ratio of V(V):foreign ions = 1:1. It was found that Fe(III) ion interfered most seriously in the determination of V(V). The experimental result was found to be in good agreement with those obtained using the ICP-AES method.
