【摘要】 <正> The extraction of copper with calixarenes was researched by comparing the results from calix[4]-,calix[6]-and calix[8]-arenes.Hie extraction ability increased as the order:calix [4]-> calix[8]-> calix[6]-arenes,with the binding ratio being 1:1.The extraction mechanism was also discussed,and itsequation Cu(NH3)42+ +H2L(0)Cu(NH3)4L(0)+ 2H+ and the extraction equilibrium constants(Ker)for calix[6]-and calix[8]-arenes were obtained respectively.
