| Abstract: | Resin adsorption technique with XAD-8 and XAD-4 was used to characterize the raw water from Er-long reservoir in Jilin province of China.The NOM chemical composition sequences of four organic fractions in the raw water,from high to low,are fulvic acid(FA)fraction,hydrophilic non-acid(HPINA)fraction.hy-drophilic acid(HPIA)fraction,and humic acid(HA)fraction.Experimental results show that FA is the,main recursor of THMFP among the four organic fractions.However,HA or hydrophobic acid exhibits the highest chlorination activity in forming THMs.It is also found that the value of FI/DOC or SUVA and the specific THMFP have better positiVe correlation.It is implied that certain source water has unique nature of NOM and DBPs. |
