Beschreibung
Zusammenfassung:The present invention relates to a process for separating a charged species from an aqueous system, wherein the process comprises the following steps: (a) a first aqueous system comprising the charged species is contacted at a first temperature with an ampholytic polymeric 5 system comprising cationic and anionic domains, wherein the charged species is bonded to the ampholytic polymeric system; and (b) the ampholytic polymeric system is contacted with a second aqueous system at a second temperature, wherein the charged species is released to the second aqueous system, wherein the second temperature is higher than the first temperature and wherein the second temperature is higher than the first temperature and wherein the second 10 temperature is less than 60° C.
