The method for determination of phosphorus pentoxide in the air of the workshop was improved. The correlation coefficient of the standard curve of phosphorus pentoxide after the improvement was 0 997, the relative standard deviation was 10 70% and the minimum detection limit was 0 2 μg / 5ml. The average The recoveries ranged from 89 5% to 105%.
