赤血盐,又名铁氰化钾 K_3Fe(CN)_6,为重要的化学试剂和化工原料。以前,赤血盐的生产均用化学氧化法,使用的氧化剂有 Cl_2、PbO_2、KMnO_4等。电化学法的特点是工艺简便,成本低廉,产品的纯度高。文献[4]中主要是以电流效率为核心,研究了膜材料、电极材料、电流密度和电解槽的温度对电流效率的影响,以及涉及阴极转动和超声场在电解过程的作用。本文旨在研究电解法制备赤血盐的条件和材料。 Red blood salt, also known as potassium ferricyanide K_3Fe (CN) _6, as an important chemical reagents and chemical raw materials. Previously, the production of red blood salt by chemical oxidation, the use of oxidants Cl_2, PbO_2, KMnO_4 and so on. Electrochemical method is characterized by simple process, low cost, high purity of the product. In literature [4], the effect of membrane material, electrode material, current density and cell temperature on current efficiency was mainly studied with current efficiency as the core. The effects of cathode rotation and ultrasonic field on the electrolysis process were also studied. The purpose of this paper is to study the conditions and materials for preparing the red blood salt by electrolysis.
