摘要：This study presents results of SEM and XRD investigation of products formed after La-rich bentonite applicationinto water containing PO43- and CO32- ions. The main product of the investigated reaction with phosphate and carbonate anionsis rabdophane-(La) and lanthanite-(La), respectively. Studied material has adaptation in many water reservoirs only forphosphorus ions reduction. Further studies might find application in case of reduction others hazardous ions. They could beprecipitated in the same fast and effective way, to other stable, nontoxic mineral phases.
