Ion exchange resin itself is not dangerous goods, when the ion exchange resin adsorbs heavy metals in water and reaches the full state, this time the ion exchange resin is dangerous goods, but it also depends on what water is used to treat, if it is only used to soften the hardness of water, then the resin is not dangerous goods when it reaches the full state. That means new, unused ion exchange resins are not dangerous.
Ion exchange resins are easy to bind and exchange with metal ions in water, but some expensive metals (such as iron and copper ions) have a strong bond with the resin. It is difficult to regenerate even with acid. Unlike non-toxic ion exchange resins, some of the active sites of the resin are occupied by metal ions, and metal ions are the poison of the ion exchange resin.
Ion exchange resins are polymeric compounds that contain functional groups (active groups that exchange ions), network structures, and insoluble polymers. When used, the ion exchange resin becomes saturated and the wastewater is backwashed with acid or base. Because the waste water after backwashing contains heavy metals, acids and alkalis, this situation is hazardous waste, but it is not too harmful to the human body.
If the ion exchange resin is regenerated after failure, the regenerants used are usually hydrochloric acid and sodium hydroxide. If the regenerant is of good quality, rinse it off after regeneration. The effluent liquid is harmless, but if the regenerator contains substances that are harmful to the human body, and the washing is not clean, it is harmful to the human body.
Ion exchange resins are non-toxic, but can become flammable when exposed to open flames or high temperatures. Therefore, store the ion exchange resin in a cool and ventilated warehouse, away from fire and heat sources, and keep the warehouse temperature below 30°C. So don't worry, ion exchange resins are non-toxic and harmless, but they must be used and cleaned properly to prevent poisoning.
