摘要： 本文研究了D2EHPA和D2EHDTPA在硝酸体系中萃取和反萃取银的条件,并用饱和法和连续变量法测定了革合物的组成,以红外光谱和核磁共振谱探讨革合物的成键情况,通过EHMO计算结果说明了上述两种革取剂对Ag+萃取能力异同的原因。
Abstract: The extraction and strip of Ag+ from nitric acid solution with Di-2-ethylhe-xylphosphoric acid(D2EHPA)and Di-2-ethylhexyldithio-phosphoric acid(D2EHDTPA) were studied.The composition of extracted complex was determined by the methods of saturation and molecular ratio. The bonding of extracted species is discussed on the basis of its IRand NMR.It is explained satisfactorily that the extraction capacities of Ag ion in the two cxtractants are quite differient by quantum chemical EHMOmethod.
