Main performance indicators:

1、 Transportation and storage of resin:

Ion exchange resin contains a certain amount of moisture, which should be maintained as much as possible during transportation and storage. If the resin loses water during storage, it should be used first

Concentrated salt water（8-10%)soak1-2After hours, gradually dilute and do not directly put it in water to avoid rapid expansion and breakage of the resin. During the storage or transportation of resin,

Should be maintained at5-40℃In a temperature environment, avoid being too cold or too hot, which may affect the quality. If there is no insulation equipment in winter, the resin can be stored in saline solution

The temperature can be determined based on the air temperature.

2、 Pre treatment of new resin:

New resins often contain solvents, substances that have not participated in polymerization reactions, and small amounts of low polymers, and may also adsorb heavy metal ions such as iron, aluminum, and copper. When resin is mixed with water, acid

When alkali or other solutions come into contact, the soluble impurities mentioned above will be transferred into the solution, polluting the effluent quality in the early stages of use. So, the new resin needs to undergo pre-treatment before being put into operation

Reason.
1. Pre treatment of Yang resin

The pretreatment steps for cation resin are as follows:

Firstly, use saturated saline solution, which is approximately twice the volume of the treated resin, and soak the resin in the saline solution18-20Hour, then drain the salt water,

Rinse with clean water until the discharged water does not turn yellow;

Next, use again2%-4%NaOHSoak the solution in the same amount as above2-4Hour (or low flow cleaning), after draining the alkaline solution, rinse the resin until the water is drained and connected

Near neutral;

Later use5%HCLThe solution, with the same amount as mentioned above, is soaked4-8After hours, drain the acid solution and drift with clean water until neutral for later use.

2. Pre treatment of Yin Resin

The steps in its pretreatment method are the same as those in the cation resin pretreatment method; Then use5%HCLsoak4-8Hour, then drain the acid solution and rinse with water until neutral; Then use2%-4% NaOHSolution immersion4-8After hours, drain the alkaline solution and wash with clean water until neutral for later use.

News report on d301 anion exchange resin gold absorbing resin

Many people have never heard of Yin before understanding the materialscation exchange resinThis material usually appears white or yellow in appearance, with a certain graininess. Its chemical equation was also obtained after long-term research in the laboratory.

Its extraction method is also relatively easy, and it can be said to be a very inexpensive material, anion and cation exchange resin. It can also be used to make water purification equipment because I need to go through multiple layers of filtration in the equipment to ensure the taste of the water quality. At the same time, it can also remove substances with relatively small particle diameters from the filtration system.

The significance of this material is that it can prevent those fish that slip through the net from appearing in the water. It can also be used to treat wastewater. Generally, wastewater needs to go through at least five layers of filtration to become relatively pure, while cation exchange resin is usually placed in the latter layer of filtration because its particles are very small. And he does not cause any pollution to the water, which can also make people who use filtering equipment feel very reassured.

A method for removing radioactive nuclide ions from water, involving a method for removing ions from water containing radioactivity. The present invention arranges multiple units between the cathode and anode, each unit consisting of a cation exchange membrane and a cation exchange resin filled between the cation exchange membranes. The filled resin is a nuclear grade resin of styrene divinylbenzene type, which has the characteristics of large exchange capacity, high conversion rate, uniform particle size, low solubility in hot water, and radiation resistance. The ion exchange resin adsorbs radioactive nuclide ions in water and migrates them to the concentrated water chamber under the action of an electric field. At the same time, some water molecules electrolyze to produce hydrogen ions and hydroxide ions, which continuously regenerate the resin. The present invention has the advantages of low production of radioactive waste resin, continuous automatic operation of equipment, simple operation and management, and easy implementation of automation control. The present invention is particularly suitable for use in radioactive water treatment in nuclear power plants.
