Abstract

The performance of new phosphate sensor was investigated using fluorescence spectrometer in the form of immobilized Al-morin on poly(glycidyl methacrylate) (pGMA) microspheres. pGMA microspheres that were synthesized by using suspension photopolymerization exhibited spherical-shaped morphology with diameters from 1.5 to 5.3 μm. The studies were carried out at pH 5 and the ratio of aluminium (III) chloride hexahydrate to morin was 3:1 (v/v). At pH 5, H2PO4 - was measured at 548 nm emission wavelength. The relative fluorescence intensity was inversely proportional to H2PO4 - concentrations. The linear range was observed between 6.6-58.8 μmol/L with detection limit (LOD) of 0.7 μmol/L. Ion interference study demonstrated that Al-morin was highly selective towards H2PO4 -.
