## Abstract The properties of gelโ€type and macroporous chelating ion exchange resins are discussed in terms of resin capacity, selectivity, and the kinetics of sorption and desorption processes. The potential application of chelating ion exchange to metal winning in leach liquor processes is discus

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
