本文用~1H-核磁共振研究了25,27-bis(carboxymethoxy)-26,28-bis(carboxyprorx3xy)-5,11,17,23-tetrakis(l,L,3,3-四甲基丁基杯[4]芳烃和25,26,27,28-四(羧甲氧基)-5,11,17,23-四(L,L,3,3-四甲基丁基)杯[4]芳烃对钠离子的萃取平衡,并在有钠离子存在或有钠离子存在的情况下研究了上述萃取剂对铜离子的萃取平衡,以阐明萃取机理及共存的钠离子对铜离子的影响。
ABSTRACT The extraction equilibrium of sodium ion with 25,27-bis(carboxymethoxy)-26,28-bis(carboxyprorx3xy)-5,11,17,23-tetrakis(l,l,3,3-tetramethvlbutyl)calix[4]-arene and 25,26,27,28-tetrakis(carboxymethoxy)-5,ll,17,23-tetrakis(l,l,3,3-tetramethylbutyl)calix[4]arene has been studied by means of 'H-NMR spectrometry. The extraction equilibria of copper (II) ion with the above extractants have also been investigated in the absence or presence of sodium ion to clarify the extraction mechanism and the effect of the coexisting sodium ion on copper ion.
