Abstract
A highly selective and sensitive optical sensor based on localised surface plasmon resonance (LSPR) of gold nanoparticles (AuNPs) for the determination of a sulphide ion in aqueous solution is presented. The existence of sulphide is change the intensity of the LSPR band around 520 nm. In this sensor, sulphide ions were recognised and measured by UV-vis spectrophotometry. Three factors such as pH, time and concentration of AuNPs have been studied. The optimisation of effective parameters is done by one at a time method. This method was simple, rapid and cost efficient for the detection of sulphide. The linear range is 1.00-10.00 (4.16-41.63 µM) ppm with the correlation coefficient of 0.9874 and the detection limit of 0.54 ppm. The relative standard deviation of the reported method is 1.01%.
