【摘要】 本文在25±1℃时考察了HDEHP-煤油/0.1M NaCl体系对Co(Ⅱ)、Mg的萃取.

【Abstract】 The extraction of cobalt ( Ⅱ ) and magnesium with di ( 2-ethylhexyl) phosphoric acid ( HDEHP ) in kerosine from 0. 1M sodium chloride solution has been studied at 25±1℃. The experimental results indicate that the reaction of extraction of Co( Ⅱ ) and Mg( Ⅱ ) with HDEHP is a cat-ionic exchange process.The general equation for extraction equilibria can be represented asThe method for calculating the free concentration of the extractant in the organic phase has been discussed.
