Description
Известные методы демеркуризации помещеиин с помощью сероводорода , хлорного железа, еоединений марганца, йода и другнх не дают хороших результатов, так как нри этом образуютс нростые соединени ртутн, обладающие высокой упругостью пара или снова дающие металлическую ртуть.The known methods of demercurization of the room using hydrogen sulfide, ferric chloride, manganese compounds, iodine, and other ones do not give good results, since this produces nano mercury compounds with high vapor pressure or metallic mercury again.
Описываемый способ лишеи указанных недостатков. Отличительной особеииостыо его вл етс применение реактивов, перевод щих адсорбированную ртуть сначала в ацидокомплексы, а затем-в трудиорастворимую соль с из анионных ацидокомплексов ртути.Describes how to lose these disadvantages. Its distinctive feature is the use of reagents that convert adsorbed mercury, first to acid complexes, and then to a labor-soluble salt from anionic acid complexes of mercury.
Над иолученными таким путем соединени ми давление паров ртути близко к нулю.Over such compounds, the pressure of mercury vapor is close to zero.
Так, например, дл демеркуризации помещений можно использовать раствор йодиодида кали и раствор дисульфитокупраата натри .For example, a solution of potassium iodide and a solution of sodium disulfite kuprakat can be used to demercurise premises.
Раствор йодиоднда кали получают путем растворени 1 г йода в концентрированном растворе 10 г йодида кали с последующим разведением до 1 л. PacTBOD дисульфитокупраата натри - путем прнливани к 1 л раствора, содержащего 35 г СиСЬ. 2Н2О 2 л раствора сульфита натри (с концентрацией 18 г/л Na2SOi. 7Н2О) и 1,5 л раствора бикарбоната натри (с коицентрацией 40 г/л МаНСОз).A solution of iodine potassium is obtained by dissolving 1 g of iodine in a concentrated solution of 10 g of potassium iodide, followed by diluting to 1 l. PacTBOD sodium disulfite kupraat - by prnlivanie to 1 liter of a solution containing 35 g CCl. 2H2O 2 l of sodium sulfite solution (with a concentration of 18 g / l Na2SOi. 7H2O) and 1.5 l of sodium bicarbonate solution (with a concentration of 40 g / l MHSO).
Помещение обрабатывают сначала первым раствором, а зател вторым.The room is treated first with the first solution, and the second one.
Предмет изобретен и The subject is invented and
Способ демеркуризации помеп еиий путем обработки химическими реагеитами, отличающийс тем, что, с целью получени соединений ртути с иизкой упругостью пара, в качестве реагентов примен ют растворы , перевод щие адсорбированную ртуть в ацидокомплексы, например , раствор йодиодида кали , и растворы, содержащие металлоион, дающий труднорастворимую соль с одним из анионных ацидокомплексов ртути, например, раствор дисульфитокупраата натри .The method of demercurization of pompacia by treating with chemical reagents, characterized in that, in order to obtain mercury compounds with ionic vapor pressure, reagents that convert adsorbed mercury to acid complexes, for example, potassium iodide solution, giving a sparingly soluble salt with one of the anionic mercuric acid complexes, for example, sodium disulfite solution.
