(373)Anion Exchange Adsorption from Aqueous Solutions of Acids by Amon Exchange Resin IV Theory of the Performance of Anion Exchange Resin Packed Column

An anion exchange resin from soybean hulls

Agricultural by-products are generally poor adsorbents of anions in solution. Therefore, modification of the by-product could enhance its anion exchange capabilities. The objective of this study was to increase the anion exchange properties of the agricultural by-product, soybean hulls, by chemical modification. Soybean hulls were quaternized with the quaternizing agent, N-(3-chloro-2hydroxypro...

Characters of Kinetic and Equilibrium of Adsorption of Eu(III) by an Cation Exchange Resin

The sorption and desorption behaviors of Eu(III) from aqueous solutions with cation exchange resins containing carboxyl groups (D155 resin) were studied in terms of varied Eu(III) concentration, adsorbent dosage, pH, contact time and temperature. Batch shaking sorption experiments were carried out to evaluate the performance of D155 resin in the removal of Eu(III) from aqu...

Extraction of Carbon Dioxide from Sea water by Ion Exchange Resin Part II: Using Strong Base Anion Exchange Resin

Compatibility between self-etching adhesive and self-curing resin by addition of anion exchange resin.

OBJECTIVE The aim was to investigate whether anion exchange resin powder in the OH(-) form, added to the amine component of self-cured resin can deprotonize acid groups of a self-etching adhesive and thus eliminate incompatibility caused by amine neutralization. METHODS Shear bond strength (SBS) of a self-cured CorePaste (COP), bonded either with all-in-one adhesive iBond (IBO) or with IBO co...

Enhanced adsorption and antifouling performance of anion-exchange resin by the effect of incorporated Fe3O4 for removing humic acid.

The application of anion-exchange resins (AERs) is limited by fouling, which increases the fresh resin dosage, regeneration frequency, and amount of regeneration effluent. In this study, five AERs with different Fe3O4 amounts was prepared by increasing the amount of Fe3O4 added to 100 g of monomer mixture for suspension polymerization from 0 g to 40 g. Results showed considerably improved pore ...
