To provide a method for recovering an acid of an anionic fluorinated emulsifier with a high yield from a basic ion exchange resin having a nonionic surfactant physically adsorbed thereon and having the anionic fluorinated emulsifier adsorbed thereon. A method for eluting and recovering an acid of an anionic fluorinated emulsifier from a basic ion exchange resin having a nonionic surfactant physically adsorbed thereon and having the anionic fluorinated emulsifier adsorbed thereon, which comprises a step (1) of bringing the basic ion exchange resin into contact with a water-soluble organic solvent and a step (2) of recovering the acid of the anionic fluorinated emulsifier from the basic ion exchange resin from which the ionic surfactant is eluted in the step (1).
摘要:
Provided is an adsorbent for removing histones from a liquid derived from a living-organism, including a water-insoluble carrier and a biocompatible polymer. The carrier has activated carbon, a polyester, a polysulfone, or a cationic functional group. Also provided is a device for purifying a liquid derived from a living-organism to remove histones from a liquid derived from a living-organism, which has a housing equipped with an inlet and an outlet for the liquid derived from the living-organism and the above-described adsorbent housed in the housing. The liquid derived from the living-organism is moved through the housing of device for purifying the liquid derived from the living-organism to remove histones from the liquid derived from the living-organism.

摘要:
A method for inhibiting formation of nitrosamines and an anion exchange resin produced therefrom comprising providing an anion exchange resin with a nitrosating agent and applying an antioxidant to the resin to inhibit formation of nitrosamines on the anion exchange resin.
摘要:
The invention provides a novel method for manufacturing iodinated resin particulates that have widespread utility as disinfectants. The invention also provides novel iodinated demand disinfectant iodinated resins that have superior properties than resins known in the art. The novel manufacturing process of the current invention is highly efficient and environmentally friendly and is conducted without the presence of water. Additionally, the manufacturing process produces iodinated resins that have better overall biological performance than resins produced by prior art methods owing to higher degrees of iodine in the manufactured resin particulates and higher degrees of uniformity of iodine content when comparing particulate to particulate.

摘要:
A method for removing phosphate ion from an aqueous solution containing phosphate ion using a resin loaded with a hydrous oxide of an amphoteric metal ion. The resin loaded with a hydrous oxide of an amphoteric metal ion is produced by combining a resin with at least two bed volumes of an aqueous solution containing a salt of the amphoteric metal ion, and having a metal ion concentration of at least 5%, and then treating with an aqueous alkali metal hydroxide solution.
