D301 is a type of macroporous strongly basic anion exchange resin. When water carrying anions flows through a resin bed, an ion exchange process occurs, where the anions in the water are swapped with the exchangeable anions (typically hydroxide ions, OH⁻) on the resin. Specifically, the tertiary amine functional groups on the D301 resin dissociate OH⁻ ions in water, rendering them weakly basic. These positively charged groups have the ability to attract and bind with anions present in the solution, facilitating anion exchange and effectively eliminating anions from the water.
Functionality: Primarily employed for the removal of anionic contaminants from water, including nitrates, chlorides, sulfates, and more. Its operational mechanism involves adsorbing anions from the water while releasing hydroxide ions (OH⁻) in return.
Physical Appearance: This resin typically presents as opaque spherical particles.
Regeneration Process: With prolonged use, the resin will reach saturation and require periodic regeneration to restore its adsorption capabilities. The regeneration process generally entails rinsing the resin with an alkaline solution (e.g., sodium hydroxide, NaOH) to dislodge the adsorbed anions, followed by rinsing to eliminate any residual alkaline solution.
D301 resin has obtained ISO9001 certification. Lingsheng Technology provides tailored services and delivers efficient and dependable ion exchange solutions across various sectors, including water treatment, metallurgy, and chemical engineering.
