巯基棉分离富集动力学荧光法测定痕量锑
摘要:
在邻苯二甲酸氢钾-氢氧化钠(KH5C8O4-NaOH)介质中,研究了Sb(Ⅲ)-KIO4-3-(2'-甲基苯基)-5-(2'-胂酸基苯偶氮)若丹宁反应体系,建立了测定锑的催化动力学荧光法。激发和发射波长为λex/λem=308 nm/409 nm,该方法的线性范围为1.67×10-11~0.01×10-6 g/mL,检出限为1.67×10-11 g/mL,方法用于实际样品中进行测定,获得满意结果。

Determination of Trace Antimony with Kinetic Fluoremetric Method Based on Separation and Enrichment by Sulfhydryl Cotton
Abstract:
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.λex/λem=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.
