摘要
对苯二酚在大气中经常以"对苯二酚粉尘"的形式存在,为了达到快速检测环境中的对苯二酚的目的,我们首先对固体对苯二酚进行了离线分析,指出了对苯二酚的特征离子峰是母体离子峰(m/z=110);然后用激光气溶胶飞行时间质谱仪对气溶胶态的对苯二酚进行了激光解吸附/电离质谱研究;并且发现杂质NaCl的加入对气溶胶态对苯二酚分子离子峰没有产生影响.
Abstract
Hydroquinone always exists in the environment by dust. For rapidly detecting it in the atmosphere, the off-line laser mass spectrometry is used to analyze the LDI mass spectra of hydroquinone firstly. And we find 110M+ is the characteristic spectrum. Then we acquire the LDI spectra of hydroquinone aerosol by aerosol time-of-flight laser mass spectrometry. Besides, no influence of impurity NaCl to the detection of hydroquinone is found, which is useful.
