“…Figure 5 depicts the impact of the molecular size on the adsorption of nitrosamines in the copper modification NaY zeolite. NDMA, NPYR, and NHMI have the molecular diameter of 0.45, 0.56, and 0.59 nm, respectively [12,24], so that the adsorbed amount of three nitrosamines is diverse. For NaY when the accumulated amount of nitrosamines arrived 1.25 mmol•g −1 , 70.5% of NHMI, 94.6% of NDMA, or NPYR could be adsorbed.…”

The latest progresses of the series of research on the trapper of nitrosamines are reported in this paper, involving the attempts to elevate the selective adsorption of zeolites through enhancing adsorbent-adsorbate interaction, in order to prepare the new functional nanoporous materials with high efficiency to eliminate the carcinogenic pollutants in environment and to protect public health. Incorporation of metal oxide such as copper oxide in NaY accelerated adsorption of volatile nitrosamines and anthracene, and moreover, coating zirconia onto the zeolite could dramatically suppress the release of nitrogen oxides in the decomposition ofN-nitrosopyrrolidine (NPYR) during temperature-programmed surface reaction (TPSR) process.

“…Incorporation of activated charcoal in cigarette filters is also effective in the filtration of mainstream smoke constituents (Polzin et al 2008;Goel et al 2018). The specific adsorption of nitrosamines was further done using other sorbents such as zeolites and mesoporous silica (Wang et al 2004;Li et al 2014Li et al , 2017Shi et al 2019;Wei et al 2009).…”
