Problems solved by technology

However, the research on the presence of heavy metals and other toxic and trace elements in cigarette smoke is currently limited to the determination of tobacco content and the study of migration rules in cigarette smoke. The possible impact of heavy metal elements in tobacco on biochemical processes in the human body has not yet been investigated. Sufficient attention has been paid to it, but less research and technology has been devoted to reducing harmful metal elements in cigarette smoke

Embodiment 1

[0015] A cigarette filter that effectively intercepts heavy metal elements is made by adding sodium chlorophyllin to ordinary cellulose acetate filter rods. First, sodium chlorophyllin is dissolved in ethanol with a concentration of 16.7% by weight, and this solution is added into triglyceride acetate with a concentration of 28.6% by weight, and the solution of triglyceride acetate is 10% by weight on the filter rod forming machine. The ratio of sodium chlorophyllin is evenly added to the opened cellulose acetate tow, so that the content of sodium chlorophyllin in the cigarette filter is 0.77 mg / piece, and a cigarette filter that effectively intercepts heavy metal elements is obtained. The cigarette filter tip manufactured by the present invention is entangled with shredded tobacco to make a sample cigarette, and a cigarette entangled with a common cellulose acetate filter tip and the same shredded tobacco is used as a control sample. The trial-manufactured cigarettes were eve...

Embodiment 2

[0019] A cigarette filter that effectively intercepts heavy metal elements is made by adding copper chlorophyllin to a common cellulose acetate filter rod. First, copper chlorophyllin is added to the triglyceride acetate with a concentration of 4.4% by weight and dispersed evenly. On the filter rod forming machine, the triglyceride solution is evenly added to the loose acetate tow at a ratio of 12% by weight. , so that the content of copper chlorophyllin in the cigarette filter is 0.85 mg / cigarette filter, that is, a cigarette filter that effectively intercepts heavy metal elements is obtained. The cigarette filter tip manufactured by the present invention is entangled with shredded tobacco to make a sample cigarette, and the cigarette entangled with common cellulose acetate filter tip and the same shredded tobacco is used as a control sample for detection. The interception effect of lead and cadmium increased by 260.3% and 56.3% (Table 2).

Embodiment 3

[0023] A cigarette filter tip that effectively retains heavy metal elements is composed of an ordinary acetate fiber filter rod and an additive filter rod. Firstly, copper chlorophyllin and sodium chlorophyllin are dissolved in ethanol composite solvent with a weight ratio of 7%, activated carbon is completely soaked in the solution to disperse evenly, and the composite activated carbon is obtained after drying. The composite activated carbon is evenly added to the opened cellulose acetate tow on the filter rod forming machine to make a feed filter rod, and the weight percentage of the composite activated carbon and the feed filter rod is controlled to be 32.7%. Composite the prepared feed filter rod with the ordinary cellulose acetate filter rod to obtain a binary composite filter tip, so that the contents of copper chlorophyllin and sodium chlorophyllin are 10 mg and 12 mg, and a cigarette filter effectively retaining heavy metal elements is obtained.

Abstract

The invention relates to a tobacco product, especially relates to a filter-tip for effectively trapping heavy metal element and manufacturing method thereof, wherein one or two kinds of copper chlorophyll and sodium chlorophyllin are added into general filter-tip. The acetic rriglyceride is added into one or two kinds of copper chlorophyll and sodium chlorophyllin and then the mixture is added into a filter stick by a filter stick molding machine, or one or two kinds of copper chlorophyll and sodium chlorophyllin are processed into granules of 40-80 mesh and then the granules are directly added into the filter stick, or one or two kinds of copper chlorophyll and sodium chlorophyllin are loaded on the active carbon and the other carrier and then added into the filter stick to form complex filter stick, namely a filter-tip for effectively trapping heavy metal element. The filter-tip can effectively trap heavy metal element with low cost and be fully suitable for industrialisation.

Description

technical field [0001] The patent of the present invention relates to tobacco products, in particular to a cigarette filter effectively retaining heavy metal elements and a manufacturing method thereof. Background technique [0002] Cigarette combustion produces about 6,000 kinds of substances. In addition to most of the organic substances, metal elements in cigarettes also enter the human body with the smoke. In food hygiene, according to metal toxicology, those metal elements that are not necessary for the human body and are easy to accumulate in the body and cause harm to the human body are collectively referred to as heavy metals. According to the recommendations of the Food and Agriculture Organization of the United Nations (FAO) and the World Health Organization (WHO), the currently controlled heavy metals include: lead, nickel, chromium, cadmium, mercury, etc. Heavy metals in cigarettes are mainly inhaled into the human body in the form of aerosols through the smoke,...
