LIQUID-LIQUID EXTRACTION, PRECONCENTRATION AND TRANSPORT STUDIES OF LANTHANUM (III) WITH CALIX [4] RESORCINARENE-HYDROXAMIC ACID (C4RAHA)
A liquid-liquid extraction and preconcentration of lanthanum (III) with a calix[4]resorcinarene bearing eight hydroxamic acid groups (C4RAHA) is described. Its analytical properties were investigated, and showed high affinity and selectivity towards lanthanum (III) in the presence of large quantitie...
