Abstract
The invention discloses an adsorbent for reducing phenol in mainstream smoke of cigarettes selectively, which is characterized in that the adsorbent is a porous oxide composite material in which Al2O3, MgO/CaO and CuO are doped into SiO2, wherein a molar ratio of the SiO2 to the Al2O3 to the MgO/CaO is 2:0.5:0.1, and CuO serving as a load accounts for 0 to 15 percent of the total mass of the adsorbent. By utilizing the characteristic of high chemical action between alkaline metal oxides and the phenol, the adsorbent has the good selective removal effect on the phenol.
Description
Technical field:
The present invention relates to a kind of adsorbent with phenol in the selectivity reducing cigarette main flume.
Background technology:
Phenol normal temperature can volatilize down, is a kind of prototype matter poisonous substance, and all life individualities are all had toxic action.Can make protein coagulating, so strong bactericidal action is arranged.It can be by directly entering blood circulation with contacting without liver detoxification of skin, mucous membrane, causes cytoclasis and lose vigor, and also can invade human body by the oral cavity, causes cellular damage.Phenol has strong corrosiveness to skin, mucous membrane, can suppress nervous centralis or infringement liver, renal function.
The phenol liquid of high concentration can make protein coagulating, and can continue to permeate in body, causes the deep tissue damage, and necrosis and even whole body are poisoned, even the aldehydes matter of low concentration also can make protein denaturation.According to relevant, phenol and other harmful substance interact and produce cooperative effect, become more harmful, promote carcinogenicization, are the carcinogenic promoting agents in the flue gas, are put into the Hoffman list.Develop a kind of filter-tip adsorbent of efficient removal phenol, effectively reducing the harmful substance contents whiles such as tar, carbon monoxide in the cigarette smoke, the content of the phenol in the selectivity reducing cigarette is highly profitable more effectively.The selection adsorption effect that is applied in the adsorbent that is used for reducing phenol amount in the flue gas in the cigarette at present is not obvious.
