Abstract：A new method for screening priority toxic organic contaminants in reclaimed water was proposed. In the procedure,combination of C18 and HLB solid-phase extraction cartridges and elution conditions were optimized. Toxic contaminants in complex matrix were characterized using both retention time lock (RTL) and deconvolution technology, and identified based on the hazardous chemical database (HCD). The recoveries of 30contaminants with log Kow between 1.48 and 6.41were from 52.1% to 138% (RSD <13.6%). The method was applied for screening the priority toxic contaminants in the reclaimed waters in Tianjin City in 2007and 2008, respectively. A total of 30toxic contaminants were identified, in which 7are regulated and 11are unregulated. Comparing their concentrations in influents, effluents and the receiving waters, it was found that the present treatment processes were not quite efficient regarding to the removal of the toxic contaminants from wastewaters.
