“…Although several researchers pointed out the drawbacks of calibrating against natural reference materials (e.g., Ujiie and Imai, 1995;Robinson et al, 1999), we believe that using a reference material as a calibration standard with appropriate reference values is worthwhile for simple and simultaneous determination by our fusion method. Moreover, in the case of future change of reference values, existing data can be corrected readily by the ratio of the revised and previous values (Eggins et al, 1997).…”

. An improved alkali fusion method followed by HF‐HNO3‐HC1O4 treatment is performed for simultaneous determination of 23 trace elements (Sr, Y, Zr, Nb, Ba, Hf, Ta, Th, U, and REE) by ICP‐MS in rock reference materials: basaltic rocks (JB‐2, JB‐3) and granitic rocks (JG‐la, JG‐2, JG‐3). Our improved method offers several advantages including: (1) suppression of whitish precipitates probably composed of insoluble fluorides by addition of HCIO4, (2) simple and reliable preparation procedure, (3) instrument calibration which enables straightforward simultaneous multi‐elemental analysis, and (4) the very low background levels by using pure lithium tetraborate flux. We obtained the analytical results with a reproducibility of mostly <2 % (1s̀) for the basaltic rocks and <7 % for the granitic rocks. The higher relative standard deviation (RSD) values for granitic rocks may be attributed to sample heterogeneity of coarse‐grained granitic rocks. The analytical results of the granitic rocks demonstrate that Zr and Hf abundances are consistent with the compiled values and that REE concentrations agree well with recently published data, suggesting that the Li2B4O7 fusion method applied in the present study is suitable for the analysis of the granitic rocks.

“…The utility of neutron activation methods, which permit measurements down to ultratrace level, is restricted by instrumentation cost, long exposure times (approximately 3 weeks) and routine analysis of numerous samples is laborious [4]. Another interesting technique for Sc determination is Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) [5]. This technique has a detection limit value for Sc of 0.05 mg/L however, its detection capability is insufficient for most scandium determination in river water samples.…”

A new adsorptive stripping voltammetric method for the determination of trace scandium(III) based on the adsorption of scandium(III)-mordant blue 9 complex on the cyclic renewable mercury film silver based electrode (Hg(Ag)FE) is presented. The effects of various factors such as: preconcentration potential and time, pulse height, step potential and supporting electrolyte composition are optimized. The calibration graph is linear from 2 nM (0.09 mg L À1 ) to 90 nM (4 mg L À1 ) for a preconcentration time of 45 s, with correlation coefficient of 0.9995. For a Hg(Ag)FE with a surface area of 7.9 mm 2 the detection limit for a preconcentration time of 90 s is as low as 5 ng L À1. The repeatability of the method at a concentration level of the analyte as low as 0.2 mg L À1, expressed as RSD is 1.9 % (n = 5). The proposed method was successfully applied and validated by studying the certified reference material (CRM 320 -river sediment) and natural samples with simultaneous recovery of Sc(III) from spiked water and sediment samples.

“…of Sc, Y and REE in reference materials: basalts (BCR-1, BHVO-1, BIR-1, DNC-1), andesite (AGV-1) and ultramafics (UB-N, PCC-1 and DTS-1). 78 Time-consuming ion exchange separation or preconcentration were found to be unnecessary. Smooth chondrite-normalized plots of the REE in PCC-1 and DTS-1 were obtained in the range 0.8-50 ng g À1 (0.01-0.1 chondrite).…”
