Abstract :
This paper describes functionalized Cu(II)-polyimidazole-modified gold (Cu(II)-PIm-Au) microelectrodes employed to measure nitrite with reduced influence of the interfering-chemicals - uric acid (UA) ascorbic acid (AA) and paracetamol (PA) - ensuring selectivity, sensitivity, stability and repeatability.
