接触二甲基甲酰胺作业工人穿戴的防护服,按不同部位剪裁后,加入溶剂,经浸泡、振荡后用不同溶剂对防护服上二甲基甲酰胺进行洗脱,取洗脱液在气相色谱仪上测定。方法线性范围0.1~5.0μg/m l,相关系数为γ=0.999 9,检出限为0.01μg/m l,洗脱效率为92.8%~95.3%,RSD为1.12%。丙酮作为防护服洗脱剂效果最佳,方法简便、快速、灵敏准确。
Contact with dimethyl formamide workers wearing protective clothing, cut according to different parts, add the solvent, after soaking, shaking with different solvents on the protective clothing on dimethylformamide, take the eluent in gas chromatography Instrument measured. The linear range of the method was 0.1-5.0 μg / ml, the correlation coefficient was γ = 0.999 9, the detection limit was 0.01 μg / ml, the elution efficiency was 92.8% -95.3% and the RSD was 1.12%. Acetone protective clothing as the best eluent, the method is simple, fast, sensitive and accurate.
