Continuous ion exchange for hydrometallurgy: Purification of Ag(I)–NaCl from divalent metals with aminomethylphosphonic resin using counter-current and cross-current operation
Continuous simulated moving bed (SMB) type ion exchange processes are usually operated in cross-current mode for metal separations whereas counter-current mode is commonly used for fine chemicals. The use of both process ...
Controlled partial neutralization of amphoteric ion exchange resin for improved metals separation
Controlled partial neutralization of an amphoteric aminomethylphosphonium functional ion exchange resin (Lewatit TP-260) was investigated. The particular goal of controlled neutralization was to replace H+ in the acidic ...
