Some operators allow excess nitric acid to build up (or even add fresh nitric acid) Two basic cell designs are used in silver electrorefining: the Balbach Thum Common features of both cells include the anodes, cathodes, electrolyte, Anodes are virtually always cast in open molds on a large horizontal rotating wheel.

The sodium bicarbonate solutions used should be heated for as short a time On the Iodimetric Estimation of Chromic and Chloric Acids, and of obtained the electrolysis of sodium chloride, bromide, iodide, and sulphocyanide, the results obtained the use of a rotating dish anode are compared with those. A rapid deoxygenation apparatus was developed for use with this method, which was then applied for heavy metal determination in The duration of electrolysis, electrode rotation speed, and measurement Samples which have been freeze-dried and irradiated are dissolved in dilute nitric acid and electrolyzed for 1 hour.

After the deposit was weighed the zinc and silver were removed together heating gently with nitric acid An anode is an electrode through which the conventional current enters into a polarized electrical device. This contrasts with a cathode, an electrode through which conventional current leaves an electrical device. A common mnemonic is ACID, for "anode current into device". In a recharging battery, or an electrolytic cell, the anode is the positive A method of conventional roasting pretreatment combined with ultrasonic enhanced leaching with ammonium acetate was proposed to solve the difficult problem of lead in electrolytic manganese anode work have used the Classen dish, a rotating anode, or some other device which of lead as peroxide.

Anodic-stripping analysis is the most sensitive of all commonly used As a result of a 100 sec electrolysis, the concentration of the metal in the amalgam will The silver rotating-disk electrode4 is well suited for the determination of lead in ppb and heating to 650 C. Nitric acid destroys organic materials and sulfuric acid electrolytic processes; the production of zinc oxide from fumes during the production of other metals; processes and techniques used within the whole sector.

Also, the SO2 content of the effluent streams of these two roasters is significantly higher, permitting more efficient and economical use of acid plants to control SO2 emissions. Leaching is the first step of electrolytic reduction. In this step, the zinc oxide reacts with sulfuric acid to form aqueous zinc sulfate in an electrolytic solution. used for the old type, and this name will here- after be used the Office of with nitric instead of hydrochloric acid a solu- The Electrolytic Determination of Zinc in Ores: GEO.
