Abstract
Inventia de fata se refera la compounduri poromerice pe baza de polimeri, constituite din bloc-copolimeri butadienstirenici elastomeri termoplastici si acizi humici în proportie de 10...70%, de preferinta 30...50%. Se conserva capacitatea de schimb ionic a sorbantului, ca urmare a inertiei chimice a suportului pe baza de bloc-copolimeri butadienstirenici si a solventului fata de sorbanti, precum si a tratamentului termic blînd la care este supus poromerul în procesul de obtinere.
