The sorption and desorption behaviour of a chelating resin containing methylamino-glucitol groups was studied for the cyano complexes of copper, silver and gold. The complexes are even extracted from solutions with an excess of cyanide. Cyanoaurate is tightly bound by the resin, but for an efficient
The sorption of yttrium and the rare earth elements (YREEs) by amorphous ferric hydroxide at low ionic strength (0.01 M V I V 0.09 M) was investigated over a wide range of pH (3.9 V pH V 7.1). YREE distribution coefficients, defined as , where [MS i ] T is the concentration of YREE sorbed by the pr
