1. the liquid functional material of HCN in a selectivity reducing cigarette main flume, it is characterized in that:

  • be obtained by transition metal ions and the aq. polyethyleneimine complexing of being rich in amino, the described polymine PEI weight average molecular weight being rich in amino is 500 ~ 100000, and aq. polyethyleneimine mass fraction is 5% ~ 40%;

    Transition metal ions is Cu 2+, Co 2+, Fe 2+/3+, Ni 2+, Zn 2+, the usage ratio of transition metal ions and PEI is 0.1 ~ 5 ×

    10 -4mol/gPEI.
