fibers.
Properties
heat-resistance, low electrical conductivity, flexibility, and high tensile strength were essential factors
The toxic properties of such fibres are dependent upon a diameter narrow enough to allow inhalation deep into the lung, a length that prevents their removal by macrophages, resistance to dissolution in tissue fluid, and a surface able to cause oxidative damage.
담배는 ‘죽음의 칵테일(lethal cocktail)’이라고 불릴 만큼 많은 종류의 유해한 물질들을 함유하고 있다. 담배연기 내의 주요 성분은 타르(tar)와 니코틴(nicotine)인데 담배 연기를 한 번 들이 마실 때에 약 50cc의 연기가 폐속으로 들어가는 것으로 알려져 있으며, 이때 이산화탄소 전량과 니코틴의 90%, 타르
Abstract
Bioethanol is one of the alternative sources of oil resources which received attention with biodiesel. Many countries produce bioethanol from food sources such as corn and sugarcane, but it causes food-energy conflicts and farmland problem. So it needs to focus on new biomass which is sustainable, renewable, cost-effective and do not occurred any conflicts. Algae are one of the bioma

To overcome the limit of old style filter
They do not work well at some circumstance.
The combination of activated carbon and zeolite has limit.
To improve performance of filter
To improve selectivity of absorbance.
To improve efficiency of filter.
- Measure both concentration of toxicsubstance.
- Compare the before and the after
- Test all three phase of toxic material
