Macroporous resin and ion exchange device for high concentration rhenium adsorption |
| abstract |
The invention discloses a macroporous resin for high-concentration rhenium adsorption. The preparation steps include: adopting a suspension polymerization method to prepare a macroporous divinylbenzene-methyl acrylate copolymer skeleton, and then chlorinating the copolymer pellets. After methylation, washing and drying, the prepared chlorine balls are soaked in methanol for swelling, and then diaminopropionic acid is added to carry out amination reaction to obtain macroporous weakly basic ion exchange resin. The invention also provides a columnar ion exchange device using the resin. A set of heat exchange components is arranged around the ion exchange column to reduce the temperature of the ion exchange column to promote the adsorption of rhenium. The ion exchange resin and device provided by the invention solve the problems of low adsorption efficiency and small exchangeable capacity of common ion exchange resin under high rhenium concentration and common operating conditions, greatly improve the efficiency of rhenium ion exchange, and promote the efficient enrichment of rhenium. collection and recycling. |
