中文摘要	a method is presented for the cloud-point extraction and separation of copper and lanthanoid ions. a water-soluble calixarene, p-sulfonatocalix[4]arene (c4as), is used as the chelating agent and triton x-100 is chosen as the surfactant. the factors affecting the extraction efficiency, such as ph, the concentrations of triton x-100 and c4as, equilibration time and centrifugation time, were evaluated. the results demonstrate that there are different extraction behaviors for cu(ii) and ln(iii). cu(ii) can be separated from ln(iii) using c4as as the chelating agent under weakly acidic conditions. the method may be used to remove trace copper from the lanthanoids.
