Abstract：For indole-3-butyric acid (IBA), the non-protected fluid room temperature phosphorescence (NP-RTP) and the fluid room temperature phosphorescence with polymeric dispersant polyethyleneglycol-200 (PEG-200), PEG-400 or non-ionic surfactant Tween-20, Tween-40, Tween-80, Tween-85, Brij35 and emulsifier OP as a medium have been studied in detail. When the surfactants or polymeric dispersants were added to the NP-RTP system, the profile of RTP spectrum was not changed, but the RTP intensity and the pre-irradiation time required to attain a stable RTP signal were increased. Whether the surfactants or polymeric dispersants were added to the system or not, no RTP signal was observed when TlNO3 was used as a heavy atom perturber (HAP), but intense RTP emissions were observed when KI was present as HAP. Recoveries of 95.2%-104% with relative standard deviations of 2.4%-4.0% were obtained in spiked water and soil samples.
