A new extractant,N-benzothiazolylazo Butyl Imide(BBI),was synthesized and identified by elemental analysis,infrared spectrum and nuclear magnetic resonance (NMR).The extraction of Pd(II) using BBI diluted with CHCl3 show high efficiency in 0-0.4M HCl medium.The dependence of the extraction percentages of Pd(II),Pt(IV)and base metal ions (Fe(III),Cu(II),and Zn(II)) on the HCl and BBI concentrations demonstrate that the idea condition for Pd(II) extraction is 0-0.4M HCl, 0.01-0.05M BBI.The stoichiometric ratio of Pd(II)-BBI complex is 1:2.The loading capacity of Pd(II) is about 0.5g/L using 0.1M BBI,which is comparable to that using DBSO.Complete stripping of Pd(II),Pt(IV) from loaded organic was proposed with 0.5M thiourea and 0.1M HCl.The Pd(II)-BBI-Cl complex has been characterized by elemental analysis,IR and 1HNMR spectra.
