ABSTRACT:
Smoking articles which use thiol-functionalized sorbents are provided. The thiol-functionalized sorbents comprise at least one thioalkylsilyl compound covalently bound to an inorganic molecular sieve substrate, where the thiol-functionalized sorbent is capable of removing at least one heavy metal constituent of mainstream smoke. The thiol-functionalized sorbents are particularly useful for the removal of mercury and/or cadmium from mainstream smoke. Methods for making cigarette filters and smoking articles using the thiol-functionalized sorbent, as well as methods for smoking a cigarette comprising the thiol-functionalized sorbent, are also provided.
