[Determination of hydrogenated terphenyls by ultraviolet spectrophotometer in the air of work place].
OBJECTIVE
To determine Hydrogenated terphenyls in the air of work place.


METHODS
Hydrogenated terphenyls in the air was collected with 40% alcohol solution and determined by ultraviolet spectrophotometer.


RESULTS
The detectable limit was 0.87mg/m3. When the concentration of standard solution was 0 - 20mg/L, the relative standard deviation (RSD) was 4.6% - 2.3%. The sampling efficiency was 97.3%. The samples were stable for 7 days.


CONCLUSIONS
It was proved that the method was fast, simple and accurate. It was suitable for the determination of hydrogenated terphenyls in the air of work place.
