摘要

EXPERIMENTAL SECTION Concentrations of alkaline-earth cations in aqueous phases were determined with a Dionex Model 10 ion chromatograph. Organic complexing agent concentrations in the CHC1, phases were measured with a Cary Model 17 ultravioletvisible spectrophotometer. Measurements of pH were made with a Fisher Accumet Model 620 pH meter using a Corning No. 476050 combination electrode. IR and'H NMR spectra were ...
