Description
несколько кристаллон фосфата цинка (затравки). 30 мик выдержки при 80°С отфильтровывали осадок фосфата цинка.a few zinc phosphate crystal (seed). 30 mic extracts at 80 ° C filtered zinc phosphate precipitate.
Пример 2. 0,5 л сульфатного раствора с рН 4, содержащего, г/л: кобальта 4,08, никел 0,10, марганца 0,15, цинка 0,19, нагревали до температуры 80°С, добавл ли 0,25 г (150% от стехиометрии) однозамещенного фосфата натри , несколько кри сталлов фосфата циика, выдерживали при этой температуре 30 мин п от()ильт|)овыпалн осадок фосфата цинка.Example 2. A 0.5 liter sulphate solution with a pH of 4 containing, g / l: cobalt 4.08, nickel 0.10, manganese 0.15, zinc 0.19, heated to a temperature of 80 ° C, 0 was added, 25 g (150% of stoichiometry) of monosodium phosphate, several phosphate crystals, were kept at this temperature for 30 min n from () ilt |) from the precipitate of zinc phosphate.
Результаты сравнительных испытаний известиого и предложенного способов приг .едены в таблице.The results of comparative tests of the lime and the proposed methods are shown in the table.
Диализ таблицы показывает, что предложенный сноеоб позвол ет сократить продолжительность процесса осаледени с 60 до 30 мик и тем самым пнтенсифицировать процесс осаждени цинка. Кроме того, контроль за посто нством рН и надежностью осаждени значительно упрощаетс , так как величина рН, онтимальна дл осаждени фосфата цинка, устанавливаете и поддерживаетс посто нной з счет буферных свойств осадител . Кроме того, введение затравки позвол ет получить кристаллический, хорошо фильтрующийс осадок.Dialysis of the table shows that the proposed procedure allows reducing the duration of the deposition process from 60 microns to 30 microns and thereby increasing the rate of deposition of zinc. In addition, monitoring the pH stability and deposition reliability is greatly simplified, since the pH value, optimal for precipitating zinc phosphate, is established and maintained constant due to the buffer properties of the precipitant. In addition, the introduction of a seed yields a crystalline, well-filtered precipitate.
