【摘要】 本文利用流动注射系统研究了由Ｊｏｎｅｓ柱产生的铀（Ⅲ）与鲁米诺之间的化学发光反应，建立了痕量铀的化学发光测定法。方法的检出限是３×１０￣（－１０）ｇ／ｍＬ铀。校准曲线的线性范围是１×１０￣（－９）～４×１０￣（－６）ｇ／ｍＬ铀，相对标准偏差为２％（测定２×１０￣（－９）ｇ／ｍＬ铀，ｎ＝１１）。对于反应机理进行了初步研究。更多还原

【Abstract】 he chemiluminescence reaction between luminoland uranium(Ⅲ)produced by Jones reductor was in-vestigated with a flow injection system. On the basisof this,a chemilumnescence method for the determina-tion of trace uranium has been established.The detec-tion limit is 3×10(-10)g/mL uranium. The linear rangeof the analytical curve is 1×10￣(-9)×10￣(-6)g/mL ura-nium,The RSD is 2%at the level of 2×10￣(-9)g/mL u-ranium(n=11).The mechanism of the chemilumi-nescence reaction has been studied preliminarily.更多还原
