综述了过渡金属铁氰化物在电分析中的应用。普鲁士蓝（铁氰化物）被认为是所有已知体系中最有前途的过氧化氢还原低电位传感器。讨论了普鲁士蓝在过氧化氢检测中优于铂电极或过氧化物酶电极的优点。各种类型的生物传感器的基础上过渡金属hexacyanoferrates和氧化酶被认为是。基于普鲁士蓝修饰电极的安培型生物传感器在流动注射模式下可以检测低至10（-7）mol L-1的葡萄糖和谷氨酸。本文概述了普鲁士蓝修饰电极在分析化学、临床诊断和食品检测中的应用前景。
The applications of transition metal hexacyanoferrates in electroanalysis are surveyed. Prussian Blue (ferric hexacyanoferrate) is recognized as the most promising low-potential transducer for hydrogen peroxide reduction among all known systems. The advantages of Prussian Blue over platinum or peroxidase electrodes for hydrogen peroxide detection are discussed. Various types of biosensors based on transition metal hexacyanoferrates and oxidase enzymes are considered. Amperometric biosensors based on Prussian Blue-modified electrodes allow the detection of glucose and glutamate down to 10(-7) mol L-1 in the flow-injection mode. The future prospects of Prussian Blue-modified electrodes in analytical chemistry for the monitoring of chemical toxic agents, in clinical diagnostics, and in food control are outlined.
