Poly(β‐Styryl)‐(1,2‐Methanofullerene‐C60)‐61‐Formo Hydroxamic Acid for the Solid Phase Extraction, Separation and Preconcentration of Rare Earth Elements

A new fullerene derivatives poly(β‐styryl)‐(12‐methanofullerene‐C60)‐61‐formo hydroxamic acid has been synthesized and applied for the solid phase extraction, separation, preconcentration and ICP‐MS determination of Ce, La, Pr, Nd, Sm and Gd. The introduction of the fullerene moiety into poly(β‐styryl)‐hydroxamic acid enhances its reactivity, chemical stability and recycled for their determination. The various parameter, viz. kinetics of sorption, breakthrough studies, effect of eluents, etc., have been studied. The influence of several diverse ions is also discussed. The proposed method has been applied for the sequential chromatographic separation of rare earths in the presence of each from rocks, monazite sand and in environmental samples.
