Abstract：

A　method　has　been　developed　for　the　determination　of　niobium　based　on　its　fluo-rescence　quenching　effect　on　rhodamine　B　(RB)-7-iodo-8-hydroxyquinoline-5-sulfonic　acid　(H2QSI)-CTMAB　due　to　the　formation　of　Nb　(　V　)-RB-H2QSI-CTMAB　complex.　The　linear　range　of　this　method　is　0.　005∼0.　12mg/L　for　Nb2O5,　the　detection　limit　is　0.　3　μg/L　and　the　precision　is1.　5%.　The　method　is　of　high　sensitivity　and　good　selectivity.　It　has　been　applied　to　the　determination　of　Nb　in　alloy　and　iron　ore　in　the　presence　of　masking　agents　with　good　results.
