PC-ANN assisted to the determination of Vanadium (IV) ion using an optical sensor based on immobilization of Eriochorome Cyanine R on a triacetylcellulose film
چکیده انگلیسی


• The design of a first colorimetric optical sensor for Vanadium (IV) monitoring in environmental water is described.
• The sensors ability to color changes and optimization the parameters influenced this determination are illustrated.
• PC-ANN is used to improve the linear range of optical sensor.
• The method is simple, sensitive, reproducible and cheap.

More detailed analytical studies of an optical sensor based on immobilization of Eriochorome Cyanine R (ECR) on a triacetylcellulose film have been described to determine Vanadium (IV) ions in some real samples. The sensor based on complex formation between Vanadium (IV) ions and ECR in acidic media caused the color of the film to change from violet to blue along with the appearance of a strong peak appears at 595 nm. At the optimal conditions, the calibration curve showed a linear range of 9.90 × 10−7–8.25 × 10−5 mol L−1. Vanadium (IV) ions can be detected with a detection limit of 1.03 × 10−7 mol L−1 within 15 min depending on its concentration. Also, the working range was improved by using PC-ANN algorithm.The sensor could regenerate with dilute acetic acid solution and could be completely reversible. The proposed sensor was successfully applied for determining V (IV) ions in environmental water and tea leaves.
