Beschreibung
Zusammenfassung:	The present invention relates to activated carbon which has a specific surface area of 1,150 m2/g to 2,200 m2/g as calculated by a BET method from the nitrogen adsorption/desorption isotherm, an adsorption amount of vitamin B12 of 10.2 mg/mL to 50 mg/mL after being in contact with 300 ppm of an aqueous solution of vitamin B12 for 24 hours, and a chlorine content of 2,500 ppm or less. La présente invention concerne du charbon actif qui a une surface spécifique de 1150 m2/g à 2200 m2/g telle que calculée par une méthode BET à partir de l'isotherme d'adsorption/désorption d'azote, une quantité d'adsorption de vitamine B12 de 10,2 mg/mL à 50 mg/mL après mise en contact avec 300 ppm d'une solution aqueuse de vitamine B12 pendant 24 heures, et une teneur en chlore égale ou inférieure à 2500 ppm. 本発明は、窒素吸脱着等温線からＢＥＴ法で算出される比表面積が、１１５０ｍ２／ｇ～２２００ｍ２／ｇであり、３００ｐｐｍのビタミンＢ１２水溶液と２４時間接触させたときのビタミンＢ１２の吸着量が、１０．２ｍｇ／ｍＬ～５０ｍｇ／ｍＬであり、塩素の含有量が、２５００ｐｐｍ以下である、活性炭に関する。
