龚洪钟等虽研制过 FeCl_4~-电极并用于盐酸中铁的测定,但关于 FeCl_4~-电极的应用报道很少,特别是食品中铁的测定,国内似未见报道,本文用 FeCl_4~-电极测定了食品中的铁,并与光度法进行了对照,结果较为满意。 Although Gong Hongzhong et al. Developed the FeCl 4 ~ - electrode and was used for the determination of iron in hydrochloric acid, few reports have been reported on the application of FeCl 4 - electrode, especially in the determination of iron in food. However, Iron in food, and compared with the photometric method, the results are more satisfactory.
