Claims (1)

Способ относится к химической технологии, в частности к получению неорганических материалов (сорбентов), и может быть использован в процессе синтеза гранулированного сорбента для селективного извлечения лития из природных рассолов и технологических солевых растворов, содержащих литий. Порошок соединения LiCl•2Al(OH)3•nH2O смешивают с раствором полимерного связующего в летучем органическом растворителе и полученную пасту экструдируют в виде гранул, содержащих после удаления растворителя от 7,5 до 10,5 мас.% полимера. В качестве полимерного связующего используют поливинилхлорид, перхлорвиниловую смолу или ацетобутират целлюлозы. В качестве растворителя - кетоны или хлорсодержащие углеводороды. Способ позволяет получать гранулированный сорбент с полной объемной емкостью 6,7-7,3 мг лития на 1 г сухих гранул. Сорбент предназначен для извлечения лития из хлоридных рассолов с pH 4-7.The method relates to chemical technology, in particular the production of inorganic materials (sorbents), and can be used in the synthesis of granulated sorbent for the selective extraction of lithium from natural brines and technological salt solutions containing lithium. The powder of the compound LiCl • 2Al (OH) 3 • nH 2 O is mixed with a solution of a polymer binder in a volatile organic solvent and the resulting paste is extruded in the form of granules containing from 7.5 to 10.5 wt.% Of polymer after removal of the solvent. Polyvinyl chloride, perchlorovinyl resin or cellulose acetobutyrate are used as a polymer binder. The solvent is ketones or chlorinated hydrocarbons. The method allows to obtain a granulated sorbent with a full bulk capacity of 6.7-7.3 mg lithium per 1 g of dry granules. The sorbent is designed to extract lithium from chloride brines with a pH of 4-7.
