离子性氟电极问世以来、测定氟的报道不断出现,但是在高含量的硫酸、硝酸、氢氟酸及杂质铬、铁、镍等存在下,测定氟的报道至今未见。现就采用氟电极测定硫酸、硝酸、铬、铁、镍等存在下的氢氟酸的方法加以介绍。 Since the advent of ion-fluorine electrodes, reports of the determination of fluorine have been reported. However, there is no report on the determination of fluorine in the presence of high levels of sulfuric acid, nitric acid, hydrofluoric acid and impurities such as chromium, iron and nickel. Is to use fluorine electrode determination of sulfuric acid, nitric acid, chromium, iron, nickel and other methods in the presence of hydrofluoric acid are introduced.
