首次用LC-MS/MS联用技术研究了4-甲基亚硝胺基-1-3-吡啶基-1-丁酮（NNK）沿着N '-亚硝基去甲烟碱（NNN）在水中的吸附。系统考察了吸附剂初始浓度、吸附时间和吸附剂种类对吸附效果的影响。首次用TG/MS和FTIR方法研究了NNK在沸石上的降解。在600 K左右，它被降解为NO、吡啶、胺和丙醛，避免了挥发性亚硝胺的形成和二次污染。
Adsorption of 4-methylnitrosamino-1-3-pyridyl-1-butanone (NNK) along withN’-nitrosonornicotine (NNN) in water is studied for the first time with the monitoring of LC-MS/MS. In the mixed aqueous solution of NNK and NNN, NaZSM-5 zeolite uniquely captured NNK but refused NNN. And the influence of initial concentration, adsorption time and type of sorbents were systemically investigated. Degradation of NNK adsorbed on zeolite is studied with TG/MS and FTIR methods for the first time. It was degraded to NO, pyridine, amine and propanal at around 600 K, avoiding formation of volatile nitrosamines and secondary pollution.
