We identified 31 disinfection by-products in chlorinated supply water, and developed a method for determining 34 halogenated by-products including three halopropionic acids with capillary column GC/ECD. Capillary column GC condition, extration solvent, pH value and effect of salt for extraction were optimized.<BR>The pH of water sample was adjustified to less than 6.0 with NaOH or H₂SO₄ after termination of residual chlorine with ascorbic acid. Sodium chloride was added with a supper saturation quantity to obtain salting out effect. Halogenated by-products were extracted with hexane (10ml×2) and then with MTBE (2.5ml×2 + 10ml) after acidifying aqueous solution with H₂SO₄.<BR>Volatile halogenated by-products in hexane and MTBE extract were analysed with capillary column GC/ECD. Nonvolatile acidic by-products were converted to methyl derivative with diazomethane, and were analysed with capillary column GC/ECD.<BR>The recoveries were 75.7118.0% for volatile halogenated by-products, except chloroaldehyde and 79.6-142.0% for nonvolatile halogenated acidic by-products on four runs. The quantitation limits of the former were 0.1μg/l except for chloroacetaldehyde (0.2μg/l) and those of the latter were 0.1μg/l except for chloroacetic acid (0.3μg/l), a -chloropropionic acid (0.3μg/l), dibromochloroacetic acid (0.5μ/l) and tribromoacetic acid (0.7μg/l) . Relative standard deviations were less than 3% for volatile halogenated by-products and less than 5% for nonvolatile halogenated acidic by-products except for dibromochloroacetic acid (10%) and tribromoacetic acid (22%) .
