摘要：

Determination of single rare earth element is relatively difficult since the properties of rare earth elements are so similar. Determination of trace amounts of yttrium in rare earth ores by adsorption catalytic polarographic has not been reported. In this paper, after several experiments, it is found that in NH3-NH4CL buffer solution which pH 9.2,yttrium, pyrocatechol violet(PV), 1.lO-phenanthroline(phen) and cetyltrimethylammniu bromide-(ClMAB) may form stable tetrabasic complex, which can produce penetrating and sensitive adsorption catalytic polarographic wave on multiple functional polarograph of PAR 384B-4.
