TI  - Assays on the simultaneous determination and elimination of chloroanisoles and 
      chlorophenols from contaminated cork samples.
PG  - 215-21
AB  - A method for the simultaneous determination of the chloroanisoles and 
      chlorophenols in cork samples with gas chromatography has been evaluated in view 
      to its application. All the stages of the suggested procedure have been submitted 
      to an in-depth examination using spiked ground corks. The recoveries of the 
      method, which involves a simultaneous extraction with n-pentane followed by a 
      second extraction using an aqueous basic solution where the phenolic derivates 
      are transferred and, subsequently, derivatised, have been satisfactory for the 
      all analytes at the studied spiking concentration levels. Good precision data and 
      limits of detection between 1 ng/g and 2 ng/g were obtained for almost all 
      compounds. As real samples, naturally contaminated cork slabs taken from 
      different sources have been analysed, showing the presence of 
      2,4,6-trichloroanisole (TCA) and, in lesser extent, its direct precursor, 
      2,4,6-trichlorophenol (TCP). Removal studies have been performed by washing these 
      tainted cork slabs with different solutions: Milli-Q water, sodium hydroxide and 
      commercial products. Sodium hydroxide solutions have led to better analyte 
      elimination, and the complete removal of TCP from the cork has been accomplished 
      together with 72% of TCA reduction has been achieved.
