When the pH value is 7.0 ± 0.5,salting-out and distillation can separate and enrich the volatile phenol and aniline in wastewater simultaneously. Six kinds of salts have been chosen for the experiment. The enrichment results of different kinds of salts have been investigated. The best kind of salt chosen is NaCl. 150 g of NaCl is used for 250 mL of water sample. The recovery rate of phenol and aniline can be as high as 92.4% and 91.5% respectively in the first 50 mL distillate. The enrichment rate is over 20 times. This method can enrich the volatile phenol and aniline effectively. It has more superiority, when they are determined in wastewater with low concentration.【Key Words】： salting-out-distillation enrichment volatile phenol aniline
