The collecting filter can capture and collect various chlorinated organic compounds in both particulate form and gaseous form contained in a fluid at the same time, and is easy to extract the collected chlorinated organic compounds therefrom. This collecting filteris provided with a fluid-permeable molded body containing fibers and an inorganic binder for binding the fibers to one another, and a hydrophobic material having higher hydrophobicity than that of the fibers and the inorganic binder, which is retained in the molded body. Various chlorinated organic compounds such as dioxins in both particulate form and gaseous form contained in the sample gas are captured and collected upon passage through the collecting filter

Filter for collecting chlorinated organic compound

Straight, nano-scale-order amorphous carbon tubes having a long-term stable ability for storing various kinds of gases and being stable in shape, and a novel process for producing said carbon tubes with high purity, high yield and high mass-productivity are provided. The amorphous nano-scale carbon tubes are prepared by subjecting a heat-decomposable resin having a decomposition temperature of 200 to 900&#xb0; C. to an excitation treatment in the presence of a metal powder and/or a metal salt, or by subjecting a carbon material containing &#x2014;C&#x2261;C&#x2014; and/or &#x2550;C&#x2550; to a heat-treatment at 3000&#xb0; C. or lower.
