Abstract
An organic-inorganic hybrid optical sensor (LQS) was prepared with post grafting of 8-hydroxy-5-quinoline sulfonic acid onto the surface of LUS-1. Its structure was characterized by powder X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), fourier transform infrared spectroscopy (FT-IR), N2 adsorption/desorption, and thermogravimetry analysis (TGA). The fluorescence evaluation of LQS toward a wide range of cations including Na+, Mg2+, Al3+, K+, Ca2+, Cr3+, Mn2+, Fe2+, Fe3+, Co2+, Ni2+, Cu2+, Zn2+, Cd2+, Hg2+ and Pb2+ revealed that LQS was a highly selective optical sensor for Fe3+ in a wide range of pH in pure water.
