A waste resin having a quaternary ammonium group (-N(CH3)3OH) on a styrene-divinylbenzene copolymer matrix, which has the characteristics of good mechanical strength and high heat resistance. Mainly used for the preparation of pure water, high purity water, wastewater treatment, extraction of biochemical products and extraction of tungsten and molybdenum in hydrometallurgy.
1. Waste resin Anion resin: mainly contains a strong reactive group such as -N+(CH3)3 having a tetrahedral ammonium salt functional group, and in the hydrogen oxygen form, the hydroxide ion in -N+(CH3)3OH- can be It is quickly released for exchange, and the waste resin anion resin can be exchanged with all anions.
2. Waste resin Anion resin: It has a weak reaction group such as an amino group, and can only remove anions such as SO42-, Cl- or NO3- in strong acid, and cannot remove HCO3-, CO32- or SiO42-. Ion exchange process (ionexchange process) is a reversible chemical reaction between ions in the liquid phase and ions in the solid phase. When some ions in the liquid phase prefer ion exchange solids, they are ion exchanged. Solid adsorption, in order to maintain the electrical neutrality of the aqueous solution, the ion exchange solid must release the equivalent ions back into the solution.
