    Abstract: 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).

    Abstract: Disclosed is a continuous process for separating or extracting proteins from a low grade mixture of a protein of interest, other proteins, impurities, and salts in a continuous simulated moving bed separation process. The invention provides for direct extraction of heme protein and plant protein from a crude mixture of such proteins, other proteins, impurities and salts using the chromatographic technique of simulated moving bed (SMB) continuous chromatography. The SMB process combines the steps of feed loading, adsorbent washing, product elution, adsorbent regeneration, and adsorbent equilibration. The novel strong anion exchange resin adsorbent is a quaternary amine cross-linked microcellulose wherein the microcellulose is cross-linked with epichlorohydrin and the quaternary amine is 2,3-epoxypropyltrimethyl-ammonium chloride which exhibits selective adsorption of proteins and complete regeneration. Purified protein separated in this manner may provide human health benefits by providing greater medicinal and nutrition opportunities from low quality protein sources.

    Abstract: Systems and methods are disclosed for extracting a plurality of materials from a solution. These include a plurality of extraction devices. The extraction devices use a resin suspended above at least one screen, and the resin is used to extract at least one material from a fluid. A liquid is forced through the plurality of extraction devices and a separate material is extracted in each of the extraction devices. The resin is selected for each of the extraction devices and is based upon the material for which that extraction device is designed to remove from the fluid. Each of the extraction devices operate in series to remove at least one material from the fluid.
