摘要：
A compact, lightweight, and portable solid-phase extraction system without a power supply was designed and constructed for the on-site pretreatment of water samples. First, the recovery rates of endocrine disruptors, such as alkylphenols and bisphenol A from a solid-phase adsorbent, were examined. The recovery rates of each analytes were almost unchanged after one-day storage. We also proposed an on-site addition of a surrogate in water samples. By this procedure it was possible to calculate recovery rates even for on-site extraction. This method was evaluated using water samples from Arakawa River. Because the quantitative value of nonylphenol (mix) by this method was higher than that by the usual method, this pretreatment method is useful and reliable for field analyses.
