The reaction system of Sb(Ⅲ)-KIO₄-3-(2'-methylphenyl)-5-(2'-arsenoxyl-phenylazo) rhodanine was studied in the medium of potassium hydrogen phthalate-sodium hydroxide,where a new method of determination trace antimony with catalytic kinetic fluoremetry was established.λ_ex/λ_em=308 nm/409 nm,the linear range is 1.67×10^-11~0.01×10^-6 g/mL,and the detection limit is 1.67×10^-11 g/mL.The method was applied to determine the real samples with satisfactory results.
