Improvement of Determination Method of Volatile Phenol in Water

Objective To improve the method to determine the volatile phenol content in water.Methods 4-An Ti-than-trichloromethane spectrophotometry was adopted,the extraction equipment was a 100 ml color comparison tube instead of a 500 ml separalory funnel water bath.Results A good linear of the method was 0.01-0.05 mg / L for volatile phenol with correlation coefficient 0.999 5.Recovery rate ranged from 87.50% to 108.10%,and relative standard deviation was1.82%-2.92%.ConclusionThe test method after improvement is simple,stable.
