| 英文摘要 | new techniques for the field detection of inorganic improvised explosive devices (ieds) are urgently developed. although ion mobility spectrometry (ims) has been proved to be the most effective method for screening organic explosives, it still faces a major challenge to detect inorganic explosives owing to their low volatilities. herein, we proposed a strategy for detecting trace inorganic explosives by thermal desorption ion mobility spectrometry (td-ims) with sample-to-sample analysis time less than 5 s based on in-situ acidification on the sampling swabs. the responses for typical oxidizers in inorganic explosives, such as kno3, kclo3 and kclo4 were at least enhanced by a factor of 3000 and their limits of detection were found to be subnanogram. the common organic explosives and their mixtures with inorganic oxidizers were detected, indicating that the acidification process did not affect the detection of organic explosives. moreover, the typical inorganic explosives such as black powders, firecrackers and match head could be sensitively detected as well. these results demonstrated that this method could be easily employed in the current deployed ims for on-site sensitive detection of either inorganic explosives or organic ones. |
