The typical weak base anion resin exchange reaction:
R-NH2 + HNO3 = R-NH3NO3
Weak base anion resins= do not remove as much silica or C02 as a strong base (used in city water deionization systems) they have great capacity and are a very good neutralizer of strong acid rinses such as nitric, hydrochloric and sulfuric that are present in many industrial metal finishing and anodizing process plating lines.

Weak base anion resin regeneration needs only to neutralize the absorbed acid, it need not provide hydroxide ions. Less expensive weakly basic reagents such as ammonia (NH3) or sodium carbonate can be employed.
Lanlang offers you a series weak base anion resin for water purification and is always passionate to provide customers with application supports. we are always glad to cooperate customers to carry out life time test, function test, extreme working condition test, etc.
