Bisphenols are an environmental concern. Exposure to bisphenols has been related to a change in the size of reproductive organs, sperm production, and the onset of puberty. UV spectroscopy can be used to determine the occurrence and concentration of bisphenols in simple solutions. Caution must be used in using UV spectroscopy when the extractant may be contaminated with another solvent or extractant. With relatively pure water samples, UV spectroscopy works well. GC-MS can be used to confirm the results in cases where there is some doubt. Syringe filters adsorb bisphenol, with PTFE generally adsorbing the least and Nylon adsorbing the most. Syringe filter filtration should be avoided when determining the concentration of BPA in solutions. If syringe filtration must be done, the results must be corrected for the adsorption of BPA by the filters. This is an abstract of a paper presented at the 2011 AIChE Annual Meeting (Minneapolis, MN 10/16-21/2011). Source
