| Abstract: | Based on the experiments,pretreatment methods for determination of volatile phenol is simplified,the pretreatment method that water sample with distilled water join the one-time distillation to pretreat is proposed.Compared with the original method,this method not only has the advantages such as save time and electricity,also has higher precision and accuracy,and has no significant differences from the original methods by statistics test. |
