Polymers selective for tobacco specific nitrosamines and methods of using the same |
摘要 |
A class of molecularly imprinted polymers that specifically recognizes and binds to TSNAs are useful, for example, in analysis and separation of TSNAs from biological fluids. Such polymers are also useful in methods of treating and manufacturing tobacco products and materials. Also disclosed are selectively adsorbent non-molecularly imprinted polymer of a non-acidic monomer and a cross-linker having polar functionality, one of which is hydrophilic, the other of which is hydrophobic, and the use of such polymers in the treatment of materials containing nicotine and nitrosamine. |

1. A method for removing nitrosamine from material containing nitrosamine, said method comprising contacting the material with an adsorbent non-molecularly imprinted polymer of a non-acidic monomer and a cross-linker having polar functionality, one of which is hydrophilic, the other of which is hydrophobic. |
