The distribution coefficient (Ko) of trace zinc in 1 M NaCl solution on an aminophosphonate-chelating resin Duolite C467 increased with pH to a peak value close to 200000 ml/g at pH about 6. At higher pH values the KD dropped to 25 000 ml/g due to competition of zinc hydrolysis. Increasing NaCl conc

The effect of a transmembrane pH gradient on the ouabain, bumetanide, and phloretin resistant H + efflux was studied in rabbit erythrocytes. Proton equilibration was reduced by the use of DIDS (125 pM) and acetazolamide (1 mM). H + efflux from acid loaded erythrocytes (pH, = 6.1) was measured in a K
## Abstract Agricultural byβproducts are generally poor adsorbents of anions in solution. Therefore, modification of the byβproduct could enhance its anion exchange capabilities. The objective of this study was to increase the anion exchange properties of the agricultural byβproduct, soybean hulls,
