D301 is a macroporous strongly basic anion exchange resin. When
water containing anions passes through a resin bed, the anions in
the water exchange with the exchangeable anions on the resin
(usually hydroxide ions OH⁻). Specifically, the tertiary amine
groups on the D301 resin dissociate OH- in water and become weakly
basic. The positive charge groups can adsorb and combine with the
anions in the solution, thereby generating anion exchange and
removing the anions from the water.
Function: Mainly used to remove anionic pollutants in water, such
as nitrates, chlorides, sulfates, etc. Its working principle is to
adsorb anions in water and release hydroxide ions (OH-).
Physical form: This resin is usually opaque spherical particles.
Regeneration: Over time, the resin will become saturated and needs
to be regenerated regularly to restore its adsorption capacity.
Regeneration usually involves rinsing the resin with an alkaline
solution (such as sodium hydroxide NaOH) to remove the adsorbed
anions, and then rinsing the resin to remove the remaining alkaline
solution.
D301 resin has passed ISO9001 certification. Lingsheng Technology
offers customized services and provides efficient and reliable ion
exchange solutions for fields such as water treatment, metallurgy,
and chemical engineering.
