Description

емкости. Навеска смолы в каждом слое 2,03г. Обща  высота центральной камеры 8 см, толщина 1,4 см, ширина 2,1 см. Центральную камеру заполн ли дистиллированной водой, через катодную и анодную камеры снизу вверх, циркулировали 0,05 н. растворы соответственно кислоты и щелочи. Регенерацию проводили в течение 3 час при силе тока 300 ма. После окончани  опыта смолу послойно перегружали в колонки и оставшиес  солевые ионы вымывались 0,5 н. раствором азотной кислоты. Степень регенерации рассчитывали по содержанию соответствующих ионов.capacity. A portion of the resin in each layer 2,03g. The total height of the central chamber was 8 cm, thickness 1.4 cm, width 2.1 cm. The central chamber was filled with distilled water, 0.05 N was circulated through the cathode and anode chambers from bottom to top. solutions of acid and alkali, respectively. Regeneration was carried out for 3 hours at a current of 300 mA. After the end of the experiment, the resin was overloaded in layers into columns and the remaining salt ions were washed out 0.5 n. nitric acid solution. The degree of regeneration was calculated by the content of the corresponding ions.

Дл  проведени  регенерации по предлагаемому способу  чейку помещали между полюсами посто нного электромагнита таким образом , чтобы на поток ионов, мигрирующих между электродами, действовала сила, направленна  в соответствии с «правилом левой руки вверх  чейки.To carry out regeneration according to the proposed method, a cell was placed between the poles of a permanent electromagnet so that the flow of ions migrating between the electrodes was acted upon by the force of the left hand upward of the cell.

Схема такого расположени   чейки с указанием направлени  магнитного пол , электрического тока и «выталкивающей силы показана на фиг. 1 и 2. Результаты регенерации ионитов при наложении магнитного пол  представлены в таблице.A diagram of this arrangement of the cell, indicating the direction of the magnetic field, the electric current and the buoyancy force, is shown in FIG. 1 and 2. The results of the regeneration of ion exchangers when a magnetic field is applied are presented in the table.

Наложение посто нного магнитного пол  приводит к существенному увеличению степени регенерации ионитов и способствует равномерности распределени  последней по высоте сло  смол. При этом с увеличением напр женности магнитного пол  растет степень регенерации. Наложение магнитного пол  позвол ет также сократить продолжительность регенерации при заданной конечной степени регенерации ионита.The imposition of a constant magnetic field leads to a significant increase in the degree of regeneration of ion exchangers and contributes to the uniform distribution of the resin over the height of the resin layer. At the same time, with increasing magnetic field intensity, the degree of regeneration increases. The application of a magnetic field also makes it possible to shorten the regeneration time for a given finite degree of regeneration of the ion exchanger.
