Abstract

A lithium-selective polymeric membrane has been immobilised on the surface of a semiconductor transducer. This light-addressable potentiometric sensor (LAPS) with the induced lithium selectivity has been prepared with the aim at further development of a Li⁺ assay in liquid media, including biological fluids. The sensor developed exhibits Nernstian response interval of 10^-5 to 10^-1moll^-1 with an ionic sensitivity of (58±1)mV/pLi. The detection limit was found to be (3±1)×10^-6moll^-1 Li⁺. The sensor has high selectivity for lithium over sodium and potassium ions with selectivity coefficients of K_Li/Na^POT=(7±2)×10^-3 and K_Li/K^POT=(5±1)×10^-3, respectively, and a response time of less than 30s.
