AB  - A new design of hyperbranched polyglycerol/graphene oxide nanocomposite 
      reinforced hollow fiber solid/liquid phase microextraction (HBP/GO -HF-SLPME) 
      coupled with high performance liquid chromatography used for extraction and 
      determination of ibuprofen and naproxen in hair and waste water samples. The 
      graphene oxide first synthesized from graphite powders by using modified Hummers 
      approach. The surface of graphene oxide was modified using hyperbranched 
      polyglycerol, through direct polycondensation with thionyl chloride. The ready 
      nanocomposite later wetted by a few microliter of an organic solvent (1-octanol), 
      and then applied to extract the target analytes in direct immersion sampling 
      mode.After the extraction process, the analytes were desorbed with methanol, and 
      then detected via high performance liquid chromatography (HPLC). The experimental 
      setup is very simple and highly affordable. The main factors influencing 
      extraction such as; feed pH, extraction time, aqueous feed volume, agitation 
      speed, the amount of functionalized graphene oxide and the desorption conditions 
      have been examined in detail. Under the optimized experimental conditions, 
      linearity was observed in the range of 5-30,000ngmL(-1) for ibuprofen and 
      2-10,000ngmL(-1) for naproxen with correlation coefficients of 0.9968 and 0.9925, 
      respectively. The limits of detection were 2.95ngmL(-1) for ibuprofen and 
      1.51ngmL(-1) for naproxen. The relative standard deviations (RSDs) were found to 
      be less than 5% (n=5).
