摘　　要：研究了新试剂4,4′-二[3-(4-苯基-2-噻唑基)三氮烯基]联苯(BPTTBP)与氯化十六烷基吡啶(CPC)的显色反应。在NaOH碱性介质中,试剂与CPC发生显色反应,形成紫色离子缔合物,最大吸收波长592 nm。试剂BPTTBP与CPC的缔合比为1∶1,其表观摩尔吸光系数为2.84×104L.mol-1.cm-1,CPC量在0~1.0×10-5mol/L范围内服从比尔定律。方法可直接用于废水中微量CPC的测定。The colour reaction of N-cetylpyridinium chloride(CPC) with 4,4′-bis[3-(4-phenylthiazol-2-yl)triazenyl] biphenyl(BPTTBP) has been studied.The results show that,in the medium of NaOH,the CPC reacts with the reagent to form a purple ion pair complex with the molar ratio of 1∶1.The complex exhibits maximum absorption at 592 nm with a molar absorptivity of 2.84×104 L·mol-1·cm-1.Beer′s law is obeyed for CPC in the concentration range of 0～1.0×10-5 mol/L.The method was applied to the determination of CPC in waste...
