TI  - Determination of thiophenols with a novel fluorescence labelling reagent: 
      analysis of industrial wastewater samples with SPE extraction coupled with HPLC.

AB  - A simple, sensitive, and selective high-performance liquid chromatography (HPLC) 
      method using 9-(2-iodoethyl)acridone (IEA) as a novel fluorescence derivatizing 
      agent for the simultaneous determination of six thiophenols has been developed. 
      An efficient Pb(2+)-modified OASIS-MCX cartridge was used and could get good 
      recoveries. IEA was successfully used to label thiophenols with high sensitivity 
      and excellent selectivity. The effects of different solvents, pH, and surfactants 
      on fluorescence properties of derivatives were investigated. To obtain the best 
      labeling efficiency, derivatizing parameters including pH value, temperature, and 
      concentration of IEA, as well as types of catalysts were also evaluated in 
      detail. Under the optimal conditions, the separation could be achieved within 12 
      min with limits of detection (LODs) in the range of 0.6-5.8 mug L(-1) and relative 
      standard deviations (RSDs) < 3.9%. This is the first time that IEA was applied to 
      the analysis of thiophenols, and the established method has been successfully 
      applied to the trace level detection of thiophenols in industrial wastewater 
      samples.
