Description
Предметом изобретени вл етс электролитический способ получени пермапганатов путем анодпого растворени ферромарганца и силикомарганца в слабокислых или нейтральных растворах сульфатов.The subject of the invention is an electrolytic method of producing permapganates by anodic dissolution of ferromanganese and silicomanganese in weakly acidic or neutral sulphate solutions.
Известен способ получени перманганатов анодным растворением указанных сплавов в щелочных растворах, однако, он не нашел примененна в промышленности ввиду пассивировани электродов .A known method for producing permanganates by anodic dissolution of these alloys in alkaline solutions, however, it was not used in industry due to the passivation of electrodes.
Описываемый способ отличаетс от известного тем. что анодное растворение производитс в растворах сернокислых солей, благодар чему не происходит пассивирование электродов .The method described is different from the known ones. that anodic dissolution is carried out in solutions of sulphate salts, due to which passivation of the electrodes does not occur.
Примеры. 1. При получении пермапганата кали из ферромарганца , содержаш,его 82,5 Мп и 8,17 Fe требуетс :Examples 1. Upon receipt of potassium permapganate from ferromanganese containing 82.5 Mp and 8.17 Fe, the following is required:
Насыш;енный раствор K2S04 Анодна плотность тока от 7 дп 15 Saturated solution K2S04 Anode current density of 7 dp 15
Напр жение на ванне 5,2-6,5 в Выход по току от 34 до 39% (в зависимости от примен емой плотности тока).Bath voltage 5.2-6.5 V Current output from 34 to 39% (depending on the applied current density).
2. При цолучении перманганата2. When pickling permanganate
кали из силикомарганца. содержаш ,его 65,47 Мп и 17,88 Si требуетс :potassium from silicomanganese. containing 65.47 MP and 17.88 Si, it is required:

3.При получении перманганата натри из ферромарганца треб етс :3. When receiving sodium permanganate from ferromanganese it is required:
Насыщенный раствор Ka2SO4 Анодна плотность тока 10 а/дмНапр жение на ааппе 5,8 в Выход по току 39,5%Saturated Ka2SO4 solution Anode current density 10 a / dm Voltage at aappe 5.8 v Current output 39.5%
4.При получении пермангапата натри из силикомарганца требуетс :4. When receiving sodium permanganate from silicomanganese it is required:
Насыш,енный раствор- NaaSO.i Анодна плотность тока 9 а/дм Напр жение на ванне 7 в Выход по току 41%Enriched, diluted solution — NaaSO.i Anode current density 9 a / dm Voltage at bath 7 v Current output 41%
