Abstract
The characterization of and construction of a new optical sensor based on the immobilization of Pyrocatechol Violet on a
triacetylcellulose membrane were described to determine bismuth(III) ions in real samples. The interaction between sensing membrane and bismuth(III) ions took place at pH 3.80 in acetate buffer solution, and the color changed from yellow to blue along with the appearance of a sharp peak at 613 nm. This optical sensor has a linear range of 4.98-47.60 μM with a detection limit of 0.853 μM. Bismuth(III) can be detected within 10 min. The working range was improved using a PC-ANN algorithm. The sensor could be regenerated with 0.1 M hydrochloric acid solution. This optical sensor is designed to determine bismuth(III) in the environmental and biological samples.
