Determination of Trace Amounts of Rare Earth Elements by ETV-ICP-AES Combined with Microcolumn Separation/Preconcentration

Abstract

Abstract: A sensitive and rapid method for electrothermal vaporization inductively coupled plasma atomic emission spectrometry determination of rare earth elements(Sc, Y, La and Yb) after separation/preconcentration by a micro column packed with immobilized 1-phenyl-3-methyl-4 bonzoyl-5-pyrazone on micro-crystalline naphthalene has been developed. Various influencing factors, such as the acidity of the aqueous solution, flow rate, volume of the sample, dimension of the micro column were investigated in detail. It was found that acetone could be used to dissolve the adsorbed material packed in micro-column. The detection limits for ETV-ICP-AES determinations of Sc, Y, La and Yb with PMBP as a chemical modifier are 14, 32, 190 and 26 pg/mL. The relative standard deviations were 3.1%, 3.5%, 4.8% and 3.4% for Sc, Y, La and Yb, respectively ( n =9, c =10 ng/mL). The Sc, Y, La and Yb contents in a standard reference material of GBW07602(GSV-2) and a real tea sample determined by the proposed method are satisfactory.

Key words: Phenyl-3-methyl-4 bonzoyl-5-pyrazone, Rare earth elements, Microcrystalline naphthalene, Electrothermal vaporization-inductively coupled plasma-atomic emission spectrometry
