Ion Exchange Capacity of Chromatographic Paper

Abstract

The ion exchange capacities of Whatman No. 1 and Whatman CM81 chromatographic papers, with and without pre-washing, were determined chromatographically using lead nitrate and lead chloride. Mean values with standard deviations are reported. Statistical analysis indicates that pre-washing with acetic acid, perchloric acid, and disodium dihydrogen ethylene, diaminetetraacetate affects the capacity by the same amount at the 95% confidence limit.
