Title (EN) METHOD OF PURIFYING OBJECT TO BE TREATED
(FR) PROCÉDÉ DE PURIFICATION D’OBJET À TRAITER
(JA) 処理対象物精製方法
Abstract: front page image
(EN)A purification method by which a fluorochemical surfactant is efficiently removed from an object to be treated which contains the fluorochemical surfactant. The method for the purification of an object to be treated comprises bringing a substance [A] into contact, in the presence of a nonionic surfactant, with the object to be treated which contains a fluorochemical surfactant and water to remove the fluorochemical surfactant, and is characterized in that the substance [A] has a relative permittivity exceeding 4 at the temperature and pressure at which the removal treatment is to be conducted and is liquid at the temperature and pressure, and that the substance [A] and the water separate into two phases at the temperature and pressure.
(FR)Il est prévu un procédé de purification permettant de retirer de manière efficace un tensioactif fluorochimique à partir d’un objet à traiter contenant le tensioactif fluorochimique. Le procédé de purification d’un objet à traiter consiste à amener une substance [A] au contact, en présence d’un tensioactif non ionique, de l’objet à traiter contenant un tensioactif fluorochimique et de l’eau pour retirer le tensioactif fluorochimique, et caractérisé en ce que la substance [A] présente une permittivité relative supérieure à 4 à la température et à la pression auxquelles on réalise le traitement d’élimination, et est liquide à ces température et pression, et en ce que la substance [A] et l’eau se séparent en deux phases à ces température et pression.
(JA)フッ素含有界面活性剤を含有している処理対象物からフッ素含有界面活性剤を効率的に除去する精製方法を提供する。 フッ素含有界面活性剤と水とを含有している処理対象物にノニオン界面活性剤の存在下に物質〔A〕を接触させて上記フッ素含有界面活性剤の除去処理を行うことよりなる処理対象物精製方法であって、上記物質〔A〕は、上記除去処理を行う温度及び圧力における比誘電率が4を超え、かつ、上記温度及び圧力において流体であるものであり、上記物質〔A〕と上記水とは、上記温度及び圧力において2相に分離することを特徴とする処理対象物精製方法である。
