Abstract: PURPOSE:To automatically remove a volatile harmful substance in a highly efficient manner by a simple apparatus by a method wherein underground water if brought into contact with the treated surface of a separation membrane obtained by treating one surface of a plastic substrate membrane with fluorocarbon gas plasma and the other surface of the separation membrane is scavenged by air to transfer the volatile harmful substance to air. CONSTITUTION:A polymer membrane 2 is laminated on the outer surface of a tubular plastic substrate membrane 1 by the plasma polymerization of a fluorocarbon. When the outside of the tubular separation membrane having this structure is brought into contact with underground water while air is allowed to flow through the separation membrane to continuously scavenge the inside of the membrane, the volatile harmful substance in underground water is transferred to air to be removed from underground water. Since the plastic substrate membrane 1 constituting the tubular separation membrane is permanently arranged in the underground water stratum of the ground, it is necessary to form the substrate membrane 1 from a material having water resistance and corrosion resistance and excellent in mechanical strength.

Abstract: PURPOSE:To obtain a dyed material rich in unconventional high-class feeling by printing a textile product with a resist size consisting of a thermally reversible high polymer and then dipping the textile product in a noble metal hydrosol containing a cationic surfactant above the phase transition temperature essential to the afore-mentioned resist size. CONSTITUTION:A textile product consisting of natural, synthetic fiber, etc., is printed with a resist size consisting of a thermally reversible high polymer, i.e., a high polymer (e.g., polyN-isopropylacrylamide) capable of phase transition from a hydrophilic (low temperature) to a hydrophobic phases (high temperature) with temperature in a state coexisting with water and the resultant textile product is then dipped in a noble metal hydrosol containing a cationic surfactant above the phase transition temperature essential to the afore-mentioned resist size to dye parts other than the above-mentioned printed part. The afore- mentioned size is subsequently removed with cold water below the phase transition temperature. The textile product is dyed to brown, violet or red color in the case of gold hydrosol and to yellow color in the case of silver hydrosol.

Abstract: PURPOSE:To certainly measure the concn. distribution in a separation membrane, by calculating the adsorbing layer corresponding to the vapor pressure of a permeable substance at definite temp. with respect to the separation membrane and detecting the concn. distribution of the permeable substance in the separation membrane on the basis of the relation with the vapor pressure in the separation membrane. CONSTITUTION:For example, a dense uniform membrane having a thickness of 25mum composed of cellulose acetate with an acetylation degree of 54.4% is used as a separation membrane, and water and ethanol are separately used as permeable substances. The transmission flow rate in a steady state to the pressure of 0-150mmHg on a transmission side at 40 deg.C is measured by collecting transmitted gases by a cold trap. In the saturation vapor pressure (water: 55mmHg, ethanol: 130mmHg) of each permeable substance at 40 deg.C, change is confirmed in a transmission mode. Subsequently, this relational curve is inversely transformed and made dimensionless to calculate the vapor pressure distribution of each permeable substance in the cellulose acetate membrane and the respective definite relative vapor pressures of water (A) and ethanol (B) are adjusted and the increase in the wt. of the separation membrane is measured to make it possible to calculate the adsorption isothermal line shown by a drawing and each concn. distribution can be clearly measured.
