 note = {application/pdf, Selenium in anode slime，was determined by the following treatment. After treating anode slime with KCI0_3-1: 1 (Vol.) HCI，selenium is quantitatively precipitated in the hydrochloric acid filtrate by addition of FeS0_4-1: 1 HC1 solution and warming on water-bath (＞80℃) for 2 hours. The selenium is redissolved with fuming nitric acid and warmed to expel nitrogen oxides.　In the solution，1 drop of Phenolphthalein solution，50％ (Wt.) KOH，0.1 N-HNO_3， and 0.1 N-KOH are successively and dropwise added until faint pink colur appeares in the  solution (pH nearly equals 8.5)， then potassium selenite solution is obtained. Add 0.1 N-AgNO_3 to the potassium selenite solution， and the selenium is quantitatively precipitated as silver selenite. After cooling with ice， silver selenite is filtered off and washed with  cold water. The excess silver nitrate in the filtrate is potentiometric baek-titrated with 0.1N?KSCN. (Indicatorelectrode is Ag，using KNO_3-bridge.)  Selenium was determined with the following accuracy. For metallic selenium， the error was士0.0001 (g,) and for selenium in anode slime，it was less than 士0.0003 (g.).},
