| Abstract: | A procedure for the simultaneous determination of palladium,rhodium,cerium and yttrium in Pt-Pd-Rh,Pt-Pd-Rh-Ce,and Pt-Pd-Rh-Y alloys by ICP-AES method was developed with the determing ranges of Cc(Y),Rh and Pd being 0.1 to 1,0.6 to 6,and 2 to 20%respectively.The relative error of less than 2%and coefficient of vari-ation of 1%were obtained.This method is simple and rapid,and can be used widely as compared with other techniques. |
