- Abstract
A novel α-zirconium phosphate/polyaniline (α-ZrP/PANI) hybrid film used as K+ ion sensor was fabricated on carbon paper by electrochemical method. Mechanisms of film formation and detection of K+ ions were also proposed. The exfoliated α-ZrP was mixed with PANI and deposited on carbon paper. The resultant α-ZrP/PANI film exhibited a good current response to K+ ion with different concentrations. It also showed a wide logarithmic linear response in detecting K+ ions in the ranges of 10−8-10−4 M and 10−4-10−2 M, respectively. The results can be attributed to the synergetic effect of α-ZrP and PANI.
