Description
В ОСНОВНОМ авт. ст. № 99924 онисан способ очистки растворимых солей цинка и кадми дл изготовлени люминофоров, от-личающийс тем, что, с целью .ускорени и упрощени процесса, очистку солей цинка и кадми осуществл ют фильтрацией водных растворов этих солей через адсорбционную колонку с насадкой, верхний слой которой состоит из смеси угл с диметилглиоксимом и нижний слой из чистого угл .BASIC Auth. Art. No. 99924 it is a method of purification of soluble zinc salts and cadmium for the manufacture of phosphors, which, in order to speed up and simplify the process, the purification of zinc salts and cadmium is carried out by filtering aqueous solutions of these salts through an adsorption column with a packing, consists of a mixture of coal with dimethylglyoxime and the bottom layer of pure coal.
Описываемый способ вл етс более простым, число хроматографических колонок уменьшено, и может быть распространен на очистку солей цинка.The described method is simpler, the number of chromatographic columns is reduced, and can be extended to the purification of zinc salts.
Особенность способа состоит в том, что раствор очищенных солей цинка и кадми последовательно пропускают через колонку с катионитом и колонку с диметилглиоксимом , смешанным с активированным углем.The peculiarity of this method is that the solution of purified zinc salts and cadmium is sequentially passed through a column with cation exchange resin and a column with dimethylglyoxime mixed with activated carbon.
Дл осуществлени способа водный расвор солей цинка и кадми , содержащих дримеси железа, меди.For carrying out the method, a water solution of zinc and cadmium salts containing iron and copper drimes.
никел и других элементов, пропускают сначала через колонку, наполненную катионитом,затем через колонку с диметилглиоксимом, смешанным с активированным углем.Nickel and other elements are first passed through a column filled with cation exchange resin, then through a column with dimethylglyoxime mixed with activated carbon.
В колонке с катионитом происходит очистка солей цинка и кадми от примесей ионов железа и меди. Во второй колонке диметилглиоксимом осаждаетс никель, а уголь очищает соли от органических примесей.In the cation exchange column, the zinc and cadmium salts are purified from impurities of iron and copper ions. In the second column, nickel precipitates with dimethylglyoxime, and coal purifies the salts from organic impurities.
Ниже приводитс пример очистки солей цинка и кадми .The following is an example of the purification of zinc and cadmium salts.

St. No. 99924, characterized in that, in order to simplify the process, the solution of the purified salts is passed successively through a column with cationite and a column with a mixture of dimethylglyoxime and activated carbon.
