[Study on method of sampling and analysis of acephate in the air].
Acephate in the air was collected with polyurethane foamed plastics, desorbed with methanl, separated with a column 2% DEGS and determined by GC-FPD. The detectable limit was 0.052 mg/m3. When the concentration of standard solution was 3-15 micrograms/ml, the relative standard deviation(RSD) was 4.5%-2.3%. The desorption efficiency was above 85%. The sampling efficiency was 100%. The samples were stable for 24 h. It was proved that the method was accurate, fast and simple. It was suitable for the determination of acephate in the air.
