A novel -zirconium phosphate/polyaniline (-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 -ZrP was mixed with PANI and deposited on carbon paper. The resultant -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 -ZrP and PANI.
