SORBENT OBTAINED ON THE BASIS OF NANOCOMPOSITE MATERIALS IN SORPTION PROCESSES
A.I.Yagubov

 

Nanocomposite materials on the basis of organic bentonite and polyvinyl pyrrolidone were produced. Characteristic properties of nanocomposite material were studied using physical methods. The use of nanocomposite materials in sorption process of heavy metal ions  (Pb2+ , Mn2+)  from model solutions was shown. It was established that under optimum conditions (рН»5, t=600C) this material exhibits selective sorption capacity (0.0029 and 0.003 mol/g) to these ions. The impact of amount of  sorbent and sorbate on sorption process (pH=5–7) of uranium isotopes (234U, 235U, 238U) from clayish suspensions with natural clinoptilolite was established. Static sorption capacity SSC=34.5 mg/g of active clinoptilolite to these ions under optimum mode was detected.
