A new Ni (II) optical chemical sensor (optode) based on immobilizing of 2-amino-1-
cyclopentene-1-dithiocarboxylic acid (ACDA) to transparent acetyl cellulose film was
developed. The sensor was fabricated by binding ACDA to a cellulose acetate film that had
previously been subjected to an exhaustive base hydrolysis. The sensing membrane is
homogeneous, transparent, and mechanically stable and showed no evidence of reagent
leaching. The membrane has good durability and response time. The detectable ...
