Abstract
General application conditions of the solid phase extraction with porous polystyrene polymer cartridges, Sep-Pak PS-1 and PS-2, were investigated.
The PS-1 and PS-2 could adsorb various organic compounds from water in several ten times to several hundred times in comparison with tC18 which is a conventional octadecylsilane adsorbent. The adsorbable volumes for the solution to PS-2 are more than ca. 70% of those to PS-1. The adsorbable volumes for single component solution of 44 compounds to the PS-1 cartridge could be shown by the function of the concentration C and the solubility in water S. The adsorbed compounds could desorb with 3ml acetone from PS-1 and PS-2. From these results, the procedure for deciding the concentration conditions for simultaneous analysis or bioassay test of various trace organic compounds in water samples was proposed. It was confirmed that various trace compounds in the river water samples could be concentrated simultaneously by the proposed conditions.
