Arkhipova, Anna Alexandrovna published the artcileSorbents with non-covalently immobilized \u03b2-diketones for preconcentration of rare earth elements<\/i><\/b>, HPLC of Formula: 4551-69-3<\/a>, the publication is Talanta (2016), 497-502, database is CAplus and MEDLINE.<\/p>\n

A comparison of the efficiency of sorbents obtained by different methods of non-covalent immobilization of \u03b2-diketones on some low-polar matrixes with respect to extraction of rare earth elements (REEs) was carried out. Sorbents containing reagent amounts of 1-8 mmol\/g can be obtained by sorption of reagents on low-polar matrixes from aqueous and aqueous-organic solutions, and the value for the maximum capacity of the sorbent correlates with the sp. surface of the matrix. Similar sorbents were also prepared by impregnating the matrix with reagent. It was found out that, under the chosen conditions, sorbents modified by extracting reagent from the aqueous solutions are more stable and extract lanthanum with higher distribution coefficients than those obtained by impregnation. We have found conditions for quant. extraction of REEs from seawater in the proposed preconcentration systems (pH 4.0, minicolumn dimensions 2\u00d710 mm, v=4 mL\/min). All REE may be quant. recovered in both ways: on modified sorbents and as complexes with reagents on unmodified matrixes. We have proposed a sorbent for lanthanum preconcentration from large volumes of water samples (500 mL). The sorbent is stable in dynamic conditions and is based on hyper cross-linked polystyrene modified with 1-phenyl-3-methyl-4-benzoylpyrazol-5-one (PMBP). Desorption could be carried out with 1-2 M HNO3<\/sub>. REEs were determined by ICP-MS, LODs achieved were in ng\/l range.<\/p>\n
