High selectivity: Strong Lewis alkalinity can achieve selective adsorption of a variety of organic/inorganic acids (no salt, sugar, protein, etc.);

Heterogeneous/in-situ adsorption: It can realize heterogeneous and in-situ adsorption of acid in organic solvent, water phase, organic solvent and other systems;

High removal rate: PPM level acids still have a good removal effect;

High cleanliness: pure organic skeleton, no organic, metal impurities, stable structure, will not introduce new impurities to the separation system;

Strong stability: acid resistance, alkali resistance, high temperature resistance, strong chemical stability;

Various desorption methods: through heating desorption method, the material can be quickly recycled, reduce the discharge of three wastes, improve economy, in addition, it can also be desorbed by organic solution and dilute lye.
