【摘要】 对比研究了α－ 萘氧乙酸（α－ ＮＯＡ） 和β－ 萘氧乙酸（β－ ＮＯＡ） 的流体室温磷光性质及有机溶剂的影响． 以ＫＩ或ＴｌＮＯ３ 作重原子微扰剂， Ｎａ２ＳＯ３ 作除氧剂， 两者均可在无保护性介质存在下发射强而稳定的室温磷光信号， 可用于分析测定． 不同有机溶剂的引入， 不仅对体系ＲＴＰ强度和ＲＴＰ强度稳定所需光诱导时间的影响不同， 且对重原子微扰剂的选择亦有一定影响． 相同条件下β－ ＮＯＡ的磷光强度比α－ ＮＯＡ 的低， 但检测限相当， 且受有机溶剂的影响比较小．更多还原

【Abstract】 A comparative study of properties of non-protected room temperature phosphorescence(NP-RTP) and effects of organic solvents for α-naphthyloxyacetic(α-NOA) and β-naphthyloxyacetic acid(β-NOA) has been carried out. Both α-NOA and β-NOA aqueous solutions can emit strong and stable RTP signal in the absence of a protecting medium by addition of KI or TlNO 3 as heavy atom pertuber(HAP) and Na 2 SO 3 as deoxygenator. A good linearity between the RTP intensity and the concentration of α-NOA or β-NOA was obtained with a detection of 10 nmol/L or 12 nmol/L respectively. The kind and amount of organic solvent added to the luminescent system not only affect the RTP intensity and the pre-irradiation time required to attain a stable RTP signal,but also the selection of HAP. Under the same conditions,the RTP intensity of the system using TlNO 3 as HAP is much stronger than that of the system using KI as HAP,but the detection limits of both systems for analytical determination are comparable. The RTP intensity of β-NOA is lower than that of α-NOA,but the influence of organic solvent on its RTP emission is also less.更多还原
