Abstract
Изобретение относитс к получению ионитов, содержащих меркаптогруппу. Изобретение позвол ет повысить сорбционную емкость ионита по ртути за счет взаимодействи эпоксидированного полихлоропрена (степень эпоксидировани 90 мол.%) с сульфидом натри в бензолдиметилформамид- ной среде.This invention relates to the preparation of ion exchangers containing a mercapto group. The invention makes it possible to increase the sorption capacity of an ion exchanger with respect to mercury due to the interaction of epoxidized polychloroprene (epoxidation degree 90 mol.%) With sodium sulfide in benzenedimethylformamide medium.
Description
Изобретение относитс к получению ионообменных сорбентов, содержащих меркаптогруппу, и может быть использовано дл извлечени т желых металлов из растворов их солей, а также дл очистки сточных вод от ртути.The invention relates to the preparation of ion exchange sorbents containing a mercapto group, and can be used to extract heavy metals from solutions of their salts, as well as to purify wastewater from mercury.
Цель изобретени - увеличениесорбци- онной емкости ионита по иону ртути.The purpose of the invention is to increase the sorption capacity of an ion exchanger by mercury ion.
Пример. К7 мл бензольного раствора эпоксида полихлоропрена, содержащего 2.1 г эпоксида полихлоропрена со степенью эпоксидировани 90 мол.%, добавл ют 14,4 г кристаллогидрата сульфида натри и 12 мл диметилформамида. Реакционную смесь перемешивают магнитной мешалкой 12ч при комнатной температуре, затем нагревают на вод ной бане с обратным холодильником при 70°С 3 ч. Полимер отфильтровывают, промывают дистиллированной водой до отсутстви Example. K7 ml of a benzene solution of a polychloroprene epoxide containing 2.1 g of a polychloroprene epoxide with an epoxidation degree of 90 mol% added 14.4 g of sodium sulfide crystalline hydrate and 12 ml of dimethylformamide. The reaction mixture is stirred with a magnetic stirrer for 12 hours at room temperature, then heated in a water bath under reflux at 70 ° C for 3 hours. The polymer is filtered, washed with distilled water until no.
сульфид-иона, затем несколько раз промывают спиртом. Дл анализа полимер сушат при 50°/2 кПа. Полученный полимер не раствор етс в воде и в органических растворител х и имеет высокую обменную емкость по иону ртути (II), равную 10,4 мэкв/г.sulfide ion, then washed several times with alcohol. For analysis, the polymer is dried at 50 ° / 2 kPa. The polymer obtained is not soluble in water and in organic solvents and has a high exchange capacity for mercury (II) ion, equal to 10.4 meq / g.
