摘　　要：研究了铁、钴、镍、铜与铋形成的普鲁士蓝及类普鲁士蓝的制备,并将它们用于修饰碳糊电极得到电化学传感器。研究表明:铁氰化钴修饰碳糊电极对H2O2有明显的电催化作用,将它用于H2O2的测定取得较好的结果,测定的线性范围为5.34×10-6～5.34×10-4mol.L-1。该电极具有灵敏度高、稳定性和重现性好等特点。In this paper, the preparation of iron, cobalt, nickel, copper and bismuth formation of the Prussia blue and analogous Prussia blue had been researched. The Prussia blue and analogous Prussia blue also be applied to modify the carbon paste electrode and results showed that the electrode modified by the cobalt formation of the Prussia blue obviously was electrocatalytie to H2O2. It was applied to detect H2O2 and the good results was obtained. The detection of line range was 5.34×10^-6～5.34×10^-4mol·L^-1 and the electrode had characteristics such as high sensitivity, good stability and repeatability.
