摘要
采用吹扫捕集-气相色谱/质谱联用法测定饮用水中6种致嗅物质,优化了吹扫捕集条件。方法线性良好,甲硫醚、二甲二硫、甲苯、异佛尔酮、癸醛、β-环柠檬醛的检出限分别为10.5μg/L、0.558μg/L、0.862μg/L、47.4μg/L、4.75μg/L、3.77μg/L,标准溶液平行测定的RSD≤10.9%,加标回收率为71.0%～125%。
The six kinds of odor chemical compounds in drinking water were determined by GC/MC with purge and trap.By optimizing purge and trap parameter,good linearity was obtained;detection limits of dimethyl sulfide,dimethyl disulfide,toluene,isophorone,decyl aldehyde and β-cyclocitral were 10.5 μg/L,0.558 μg/L,0.862 μg/L,47.4 μg/L,4.75 μg/L and 3.77 μg/L separately;RSD of parallel standard solution was≤10.9%;spiked recoveries were between 71.0% and 125%.
