摘要： PROBLEM TO BE SOLVED: To provide a method and an apparatus for desorbing polychlorinated biphenyls(PCBs) from used active carbon in a manner that the residual PCBs can be eliminated without fail while any harmful products are prevented from being formed. SOLUTION: Active carbon on which PCBs have been adsorbed is fed into an air-tight reaction treater 1 and is subjected to a pretreatment for removing adsorbed water, adsorbed volatile organic gases, and air at 200 deg.C or below. The treater 1 is evacuated and is brought into an adiabatic state. The carbon is then gradually heated by allowing a current to directly flow into electrodes 8 and 9, whereupon the PCBs are removed and recovered in turn as a result of their evaporative desorption in order of increasing boiling points after the lapse of a definite retention time at every specified temperature rise in the range of 200-600 deg.C. A minor amount of the residual PCBs are gasified or carbonated at 750 deg.C or below.

摘要： PROBLEM TO BE SOLVED: To obtain a high sensitivity radiation sensitive material which shows a chromagnic change even against low level radiation, by using an acid generating material which generates an acid when the material is cracked by irradiated radiation and a pigment which develops a color or changes in color due to the generated acid as the main components of the material. SOLUTION: A radiation sensitive material is composed mainly of an acid generating material which generates an acid when the material is cracked by irradiated radiation and has the skeleton expressed by formula I and a leuco pigment or pH indicator which develops a color or changes in color due to the generated acid. The ring A, ring B, and X in the formula respectively represent a five- or six-ring aromatic ring, a heterocycle, and an anion. Consequently, when a sensitive inspection means manufactured by scattering the acid generating material having the skeleton expressed by formula I and a leuco pigment or pH indicator in a solvent or carrier is used, radiation can be detected by visually confirming the occurrence of color development or color change in the inspection means which develops a color or changes in color when the means is irradiated with radiation.
