Application method of special resin for extracting amino acid

Abstract

The invention relates to an application method of special resin for extracting amino acid, and relates to the technical field of resin. The application method is characterized by comprising the following steps in sequence: (1) enabling 3% to 4% dilute hydrochloric acid (HCL) to dynamically flow by resin at a flow rate of 5m / h, wherein the consumption of the hydrochloric acid solution is at least 1.5 times of the volume of the resin; (2) replacing the hydrochloric acid, then washing the resin by utilizing soft water until the pH value of the resin is neutral; (3) then washing a regenerative agent by utilizing soft water until the pH value of water discharged from the resin is 4 to 7, and then utilizing the resin; (4) running normally, controlling the flow rate of an amino acid fermenting solution, and controlling the retention time of the amino acid fermenting solution in a resin column at 30 to 40 minutes; (5) washing away free impurities by utilizing pure water or salty water resin; (6) washing amino acid in the resin by utilizing 5 to 8 ammonia water. The method is convenient and reasonable to operate, the adsorption capacity of the resin for extracting the amino acid can be sufficiently realized, and the service life can be prolonged.

Description

Technical field: [0001] The invention relates to the technical field of resins, in particular to a method for using a special resin for amino acid extraction. Background technique: [0002] Adsorption resin is a resin adsorbent characterized by adsorption and has a porous three-dimensional structure. It is a newly developed porous resin in the field of polymers in recent years. It is made of monomers such as styrene and divinylbenzene in the presence of organic solvents such as toluene. Small circles like fish roe are prepared by suspension copolymerization. ball. Adsorbent resins are often used in the fields of sewage treatment and extraction. The existing resins used for amino acid extraction, improper operation in the process of normal use can not give full play to the adsorption capacity of the resin used for amino acid extraction, resulting in low adsorption efficiency of the resin used for amino acid extraction, and it is easy to breed a large number of Bacteria gen...
