Title:
ADSORBENT AND FILTER MEDIA AND UTILIZATION OF THE SAME
Document Type and Number:
Japanese Patent JP2710198
Kind Code:
B2
Abstract:
PURPOSE: To collect and recover materials in a gas phase or liquid phase and to purify and classify the gas phase or the liquid phase by using carbon nanotube as an adsorbent or a filter media.
CONSTITUTION: The nanotube is physically and chemically stable, has easily wettable property that is important from the viewpoint of adsorption and is high in adsorbability. Furthermore, the carbon nanotube forms for oneself a high density fine three dimensional narrow pores by integrating oneself and has not only absorptivity of molecular level but filtration function of fine particle level. And the nanotube is capable of being regenerated as the adsorbent or filter media. The example of collection and classification of a benzene aq. solution by the nanotube is shown in the followings. A spectrum A is a spectrum of the benzene aq. solution before the adsorption by the nanotube, B is spectrum after adsorption, C is a spectrum at the half way of the saturation of adsorption. The nanotube has high adsorption to benzene and then the materials in the liquid phase are removed and the liquid phase is purified.
