    • An apparatus and method for the process of applying palladium salts to tobacco cut filler and other smokable products so that polycyclic aromatic hydrocarbons (PAHs) can be reduced in both mainstream (MS) and sidestream (SS) cigarette smoke. The reduction in PAHs is observed in the total particulate matter (TPM) of the mainstream (MS) and sidestream (SS) smoke. Additionally, substantial reductions in heavy metals and Ames biological activity can be achieved when the palladium salt solution is applied and processed in accordance with the present invention. The present invention provides these improvements by using a preferred ratio of palladium (Pd) salt to Chloride (Cl) that is specifically designed to allow for high palladium solubility. Further, the present invention provides an apparatus and method for applying the palladium salt solution while minimizing the number of processing steps required.
    • 用于向烟草切割填料和其他可吸收产品施加钯盐的方法的装置和方法,使得主流(MS)和侧流(SS)香烟烟雾中的多环芳烃(PAH)可以减少。 在主流(MS)和侧流(SS)烟雾的总颗粒物(TPM)中观察到PAH的降低。 此外,当根据本发明施加和加工钯盐溶液时,可以实现重金属和Ames生物活性的显着降低。 本发明通过使用钯(Pd)盐与氯化物(Cl)的优选比例来提供这些改进,其被特别设计成允许高钯溶解度。 此外,本发明提供了一种在最小化所需处理步骤的数量的同时施加钯盐溶液的装置和方法。
