本文在Na_2SO_3化学除氧的十二烷基硫酸钠胶束体系中,以TINO_3为重原子微扰剂,进行了苊的室温燐光法(RTP)测定。研究发现样品温度对RTP发射强度有影响,重原子TI/SDS有一个临界比率值,为30％,达到此临界比例值后能获得高的RTP值。介质pH、Na_2SO_3、SDS及TINO_3浓度不仅影响RTP强度,而且影响体系的除氧速度,最佳pH范围介于6.7～7.5之间,分析校正曲线在1×10~6～5×10~5 mol/L之间呈良好的线性关系,检出限浓度为1×10~6 mol/L。 In this paper, Na_2SO_3 chemical deoxygenation sodium dodecyl sulfate micellar system, with TINO_3 as a heavy atom perturbation agent, carried out the 苊 room temperature cofractometry (RTP) determination. It is found that the sample temperature has an influence on the emission intensity of RTP. The critical atom ratio of heavy atom TI / SDS is 30%, and a high RTP value can be obtained after this critical ratio is reached. The medium pH, Na_2SO_3, SDS and TINO_3 concentrations not only affected the RTP intensity but also affected the deoxygenation rate of the system. The optimum pH ranged from 6.7 to 7.5. The calibration curves were in the range of 1 × 10 ~ 6 ~ 5 × 10 ~ 5 mol / L showed a good linear relationship between the detection limit concentration of 1 × 10 ~ 6 mol / L.
