摘要
以抗坏血酸亚硫酸氢钠代替氯化亚锡甘油溶液测定车间空气中三氯化磷含量，剩余标准差为0.0015，标准曲线相关系数在0.9990～0.9998之间，平均回收率98.9％，相对标准偏差为3.18。
The content of phosphorus trichloride in the air of workshop is surveyed by using ascorbic acid dissolv ing in the sodium bisulfite solution to substitute glycerol stannous chloride solution.The calibration graph is linear in the range of 2.5～50μg [phosphoric acid],the remanent standard deviation is 0.0015,the correla tion coefficient is in the range of 0.9990～0.9998,and the average recovery is 98.9%,with a relative stan dard deviation of 3.18%.
