A sensitive optical sensor for determining Hg۲+ concentration has been prepared by incorporating the indicator dye, diphenylcarbazone compound, into cellulose acetate polymer film. To prepare the sensor, a cellulose acetate film was hydrolyzed with base and then the diphenylcarbazone compound bonded to the film. This method is easy to perform and uses acetyl cellulose as a carrier. According to the results, the prepared sensor was able to determine the Hg۲+ concentration with a ±۶% error. Also, the adsorption capacity was ۳.۴۱ × ۱۰-۳ mmol/g.©۲۰۱۹ jourcc. All rights reserved.
