Abstract: The invention provides an anticancer agent adsorbing sheet body that exhibits a sufficient effect of adsorbing and retaining highly toxic chemical agents such as anticancer agents, and that further improves safety for health care professionals in medical environments.

Abstract: There is provided a nitrogen analyzing method for quantitative analysis of nitrogen in a specimen by a chemiluminescence method using ozone which is capable of measuring a concentration of nitrogen contained in the specimen with still higher accuracy, as well as a nitrogen analyzer used for practicing the analyzing method. Also, according to the present invention, there is provided a nitrogen analyzing method and a nitrogen analyzer which have a less adverse influence on human body and are also capable of further reducing environmental burden even when analyzing nitrogen in fuel-related specimens.

Abstract: A current collector for a secondary battery (1) of the present invention includes a resin layer (2) having electrical conductivity, and an ion barrier layer (3) provided on the surface of the resin layer (2). The ion barrier layer (3) contains ion trapping particles (6) in which metal compounds (5) are provided on the surfaces of metal containing particles (4). The ion trapping particles (6) are continuously provided from an interface (7) between the resin layer (2) and the ion barrier layer (3) toward a surface (3a) of the ion barrier layer (3). Thus, the ion barrier layer (3) prevents from the entry of ions, so that the ion adsorption in the current collector (1) can be decreased.
