The Effect of Metal Ions on the Removal of Natural Organic Acids by Bi-Functional Resin

Abstract:

In this paper, based on the previous studies of natural organic acids adsorbed onto bi-functional resin, the influence of metal ions on the adsorption of humic, tannic and gallic acids by bi-function resin WJN-06 were systematically investigated. Low concentration of Ca²⁺ and Mg²⁺ in solution could decrease the resin’s adsorption capacity for gallic acids, but increased the removal rate of humic and tannic acids. Low concentration of Cu²⁺ and Pb²⁺ in solution could enhance the uptake of these three natural organic acids. However the high concentration of metal ions in solution could decrease the adsorption capacity of bi-functional resin for humic, tannic and gallic acids.
