Abstract

p-phenylene-2,5-benzobisoxazole (PBO; Zylon$(R)$) fibers as an adsorbent were employed for solid phase extraction of aqueous alkylphenols. The removal ratios for 10 kinds of alkylphenols at initial concentration of $100{\mu}gL^{-1}$ were in the range of 16.8-96.3% and the removals increased with the increase of the phase ratio (fiber weight/solution volume). The plots of the logarithm of partition coefficient (log K) were correlated with the logarithm of the n-octanol/water partition coefficient (log P). The adsorbed alkylphenols were completely desorbed with the mixture of acetonitrile and dichloromethane.

흡착제로서의 PBO 섬유가 수용성 알킬페놀 화합물의 고상 추출용으로 사용되었다. 초기농도 $100{\mu}gL^{-1}$ 에서 10 종류의 알킬페놀에 대한 제거율은 16.8~96.3%였고, 제거율은 섬유무게/액체부피비의 증가에 따라 증가하였다. log K는 log P와 일치하였다. 흡착된 알킬페놀은 아세트니트릴과 디클로로메탄의 혼합액으로 충분히 탈착되었다.
