Description
Дл получени качественных свет щихс составов необходимо иметь соли (сульфиды или «арбонаты) высокой чистоты с содержанием т желых металлов менее 0,0001%, в том числе железа менее 0,00002%. Дл изготовлени таких солей из водорастворимых солей металлов второй группы (нитратов, сульфатов, хлоридов ) и осадителей (углекислого аммони , натри ) обычно пользуютс химически чистыми материалами, весьма дорогими и дефицитными.In order to obtain high-quality luminous compounds, it is necessary to have high purity salts (sulfides or "arbonates) with heavy metals less than 0.0001%, including iron less than 0.00002%. For the manufacture of such salts from water-soluble metal salts of the second group (nitrates, sulphates, chlorides) and precipitating agents (ammonium carbonate, sodium), they usually use chemically pure materials that are very expensive and scarce.
Предлагаетс способ очистки технических водорастворимых солей металлов второй группы от железа, а также и других т желых металлов , позвол ющий получать кондиционные дл производства светосоставов соли.A method is proposed for purification of technical water-soluble metal salts of the second group from iron, as well as other heavy metals, which makes it possible to obtain salts suitable for the production of light compositions.
Водорастворимую техническую соль металла второй группы раствор ют в воде в фарфоровом котле на 150 л так, чтобы получить концентрацию от 200 до 250 г/л, счита на безводную соль. При наличии больших количеств нерастворивщихс примесей последние отдел ют фильтрацией через достаточноThe water-soluble technical salt of the metal of the second group is dissolved in water in a 150 l porcelain boiler so as to obtain a concentration of from 200 to 250 g / l, calculated as an anhydrous salt. In the presence of large amounts of insoluble impurities, the latter are separated by filtration through sufficient

В раствор добавл ют окислитель (перекись водорода, гипохлорит натри или кальци , хлорную известь или др. подобные вещества) в количестве, достаточном дл окислени всего железа до трехвалентного состо ни . Затем при посто нном перемешивании в окисленный раствор добавл ют свежеосаждепную гидроокись магни в количестве от 10 до 30 г Mg (ОН)2 на 1 кг сухой соли.thick fabric (eg canvas). An oxidizing agent (hydrogen peroxide, sodium or calcium hypochlorite, bleach, or other similar substances) is added to the solution in an amount sufficient to oxidize all the iron to the trivalent state. Then, with constant stirring, freshly precipitated magnesium hydroxide is added to the oxidized solution in an amount of from 10 to 30 g of Mg (OH) 2 per 1 kg of dry salt.

The iron content after such purification is less than 0.00002% in terms of dry salt. The solutions are filtered through paper filters and to free them from other heavy metals, ammonium sulphide prepared from gaseous ammonia and hydrogen sulphide is introduced in an amount of 1 g per 1 kg of salt and left to the daily sludge. After purification, the content of heavy metals is less than 0.00002%.
