Some organic matter that have aromatic structure similar as humic acid are selected to conduct chlorination test, determined the formation of HAAs and THMs of tested matters, researched the relationship of the chemical structure of DBPFP with DBPs formation characteristics. The results indicated that: (1) The sequence of HAAs formation activity is p-Hydroxybenzoic acid > p-Aminoacetophenone > o-Benzenediol > m-Benzenediol; and THMs' s is m-Benzenediol > p-Aminoacetophenone > 2-Hydroxy-p-aminoacetophenone > p-Hydroxybenzoic acid. (2) The sequence of earlier chlorination reaction rate of HAAs is m-Benzenediol > p-Aminoacetophenone > p-Hydroxybenzoic acid > o-Benzenediol; and THMs' s is p-Hydroxybenzoic acid > 2-Hydroxy-p-aminoacetophenone > m-Benzenediol > p-Aminoacetophenone. (3) The substances that having the substituent group structure of para and ortho position are mostly format HAAs, and one's of having meta position are mostly format THMs. (4) On the benzene ring, hydroxyl group has the highest activity of forming DBPs, and the second is ketone group; amino-group is play a part of auxiliary forming para, ortho or meta position structure mainly; aldehyde and carboxyl group are inert function group; the function of methyl group is remain to be determined.
