摘要：

Strong-base anion exchangers with capacities ranging from 0.04 to 1.46 mequiv./g were prepared from macroporous polystyrene-DVB resins. The capacities were controlled by varying the time of chloromethylation. Distribution ratios of anions decrease with decreasing resin capacity, but selectivity coefficients are essentially constant over the range of capacities studied. The low-capacity resins are shown to be useful for practical chromatographic separations of anion mixtures. © 1979.
