Gas sensitivity of polyaniline/SnO2 hybrids to volatile organic compounds GENG Li-na(耿丽娜) Department of Chemistry, Hebei Normal University, Shijiazhuang 050016, China Received 10 August 2009... mixing. Compared with single PAn and SnO2, the gas sensitivity of PAn/SnO2 materials to volatile organic compounds (VOCs, methanol, ethanol and acetone) was studied. The possible response mechanism......
and the purified solution were measured. The organic solution was prepared by dissolving appropriate trialkyl amine (hereafter as N235) and TBP in 50% distilled kerosene (bp 165-190 ℃). The effect of HCl... Chemical background Pretreatment of N235 with HCl solution led to the formation of amine salt with the reaction: where R3N represents N235 and subscript "org" the organic phase. The extraction......
