Selective extraction of cobalt(II) from aqueous solutions with phosphinic acid extractants |
摘要 |
Cobalt(II)-, nickel(II)-bearing aqueous solutions may be treated with an extractant comprising an organic-soluble phosphinic acid, or a salt thereof, to separate the cobalt(II) from the aqueous solution. Typical extraction techniques compatible with the instant process include liquid- liquid extraction employing either mixer settlers or columns, packed beds of supported extractants as in ion exchange, liquid membrane extraction and selective supported membrane extraction.
