Embodiment 1

[0040] The complex type macroporous ion exchange resin prepared in Examples 1-3 has a good trapping effect on nanometer copper; figure 1 After the complexed macroporous ion-exchange resin prepared in Example 1 was treated with hydrazine hydrate to reduce the filtrate to prepare nano-copper, the resin was washed with absolute ethanol, vacuum-dried, and field emission electron scanning microscopic analysis photos were taken. From figure 1 It can be seen that a large number of nano-copper particles are enriched on the surface of the resin.

[0041] From figure 2 It can be seen that the complexed macroporous ion-exchange resin prepared in Example 1 turns reddish-brown in color after treating the filtrate prepared by reduction of hydrazine hydrate to prepare nano-copper, see figure 2 (a); while the resin before adsorption is light yellow, see figure 2 (b); The complex type macroporous ion exchange resin has a good trapping effect on the copper particles in the filtrate for prep...

Abstract

The invention relates to complexing type macroporous ion exchange resin and a preparation method thereof. Macroporous ion exchange resin is used as a base material, unsaturated monomers which contain coordinating groups are in free radical copolymerization on the surface of the ion exchange resin to carry out graft modification on the macroporous ion exchange resin by high-energy ray irradiation, and the complexing type macroporous ion exchange resin with a large amount of coordinating groups on the surface is prepared; cation exchange resin, anion exchange resin and chelating ion exchange resin which use cross-linked polymer as a framework can be modified, the complexing type macroporous ion exchange resin is suitable for gathering colloidal particle, nano metallic oxide and nano metal particles, and requirements of water treatment and resource recycling of the special industry are met. The process is simple and speedy, and small-batch and multi-varieties complexing type macroporous ion exchange resin which meets different functions can be industrialized.

Description

technical field [0001] The invention relates to a preparation method of a complex type macroporous ion exchange resin, which belongs to the technical category of functional polymer materials. [0002] technical background [0003] The ion exchange resins currently produced and sold on the market are based on cross-linked polymers (such as styrene / divinylbenzene resin) as the skeleton, and the ion exchange functional groups include sulfonate and carboxylate-based cation exchange resins, quaternary ammonium salts The main anion exchange resin, and the chelating resin (or complex resin) based on the coordinating groups such as amino and acetic acid, and there are also -OH, -NH 2 complex resin. This kind of resin has a common feature, which is suitable for ion exchange. It is not effective for enriching particulate substances with charges on the surface, such as colloidal particles, nano-metal oxides, and nano-metal particles. [0004] In order to meet the needs of the environ...
