BS>Cellulose powder treated with tri-n-octylphosphine oxide (TOPOC) is prepared and applied to column chromatographic separations of elements. The possibility of separating different ionic forms of the same element is also shown as well as that of selectively extracting and concentrating trace amounts of elements from dilute solutions. The following separations are described: Fe/sup 3+/- Co- Ni; U/sup 6+/- ThLa; La-Th- Zr; Al- Cu- Fe/sup 3+/- U/sup 6+/; Pb- Bi- Fe/sup 3+/; CuBi-Sc- U/sup 6+/; Y-Th-Sc; Ni- Pd- Pt- Au; Mn- Bi-Hg; As/sup 3+/- Sb/sup 3+/; V/sup 4+/-Ti; Fe/sup 2+/- Fe/sup 3+/; Cr/sup 3/< s+>s- Cr/sup 6+/; U- Th (traces) from Fe-Ti; U and Th from dilute solutions and from solutions containing several extraneous elements. The favorable results and advantages previously given by cellulose treated with tri-n-octylamine (TOAC) are confirmed with TOPOC. (auth)
