"Study On The Flow Injection Analysis ICP-AES Spectrographic Method. 1. Determination Of Fourteen Rare Earth Impurities In High-purity Yttrium Oxide"
J. Rare Earths 1988 Volume 6, Issue 1 Pages 65-69
Chen, Hao; Jiang, Zucheng; Zen, Yune; Kong, Linying (SFS)

Abstract: Flow-injection analysis-inductively coupled plasma-atomic emission spectrometric (FIA-ICP-AES) method for the determination of 14 rare earth impurities in high-purity yttrium oxide was developed. The effects of some factors including length of transportation tube, volume of sample, exposure time, ICP working parameters, acidity and matrix concentration. were investigated. The dispersion ratio of FIA-ICP-AES method for the given condition was calculated from experimental results. Under optimum conditions the detection limits of different impurities in the method proposed are from 0.25 to 12.5 to mg/g and relative standard deviation in the range of 1.0-2.9%. This method was used for the determination of trace amounts of rare earth impurities in 99-99.99% of yttrium oxide, and their results are in good agreement with those obtained by continuous pneumatic nebulization (CPN)-ICP-AES method. In comparison with the CPN-ICP-AES method, the FIA-ICP-AES is superior in efficiency, precision, influence of acidity and matrix effect, atmosphere of sample used, and permissible concentration of salt. The sensitivity loss in FIA-ICP-AES can be compensated by increasing matrix concentration. in solution This method can be applied to the routine analysis in the rare earth industry. (SFS)

"Speciation Of Aluminum In Drink Samples By 8-Hydroxyquinoline Loaded Silylanization Silica Gel Microcolumn Separation With Off-Line ICP-MS Detection"
J. Agric. Food Chem. 2004 Volume 52, Issue 23 Pages 6843-6847

Abstract: A technique using a flow injection microcolumn separation coupled with ICP-MS detection has been developed for the speciation of Al in drink samples. The retention behaviors of different Al species were studied with 8-hydroxyquinoline (8-HQ) loaded silylanization silica gel as the packing material and inorganic acid (HNO3) as the elution. The results indicated that in a pH range of 5.0 to 8.0, all labile monomeric Al species were retained on the microcolumn while nonlabile monomeric Al species were directly passed through the column. Various Al species after separation were detected by ICP-MS. The detection limit of 0.2 ng mL-1 and a relative standard deviation (RSD) of 4.2% at 10 ng mL-1 (n = 11) were achieved, and the recoveries for the spiked samples were 95-108%. The proposed method has been applied to the analysis of Al species in tea infusions, coffee, and tap waters with satisfactory results. The results obtained by this method were compared with that obtained by the cation exchange microcolumn separation and ICP-MS detection system, and some valuable conclusions were drawn.

"Micro-column Separation/preconcentration Combined With Fluorinating Electrothermal Vaporization-inductively Coupled Plasma-atomic Emission Spectrometry For Determination Of Ultratrace Rare Earth Elements"
J. Anal. At. Spectrom. 2000 Volume 15, Issue 6 Pages 759-761

Abstract: A new method for the determination of ultratrace amounts of lanthanum, europium, yttrium and ytterbium by micro-column separation/pre-concentration combined with fluorinating electrothermal vaporization-inductively coupled plasma-atomic emission spectrometry (FETV-ICP-AES) has been developed. The 2-ethylhexyl-hydrogen-2-ethylhexyl phosphonate (P507) resin was used as the stationary phase. Various factors influencing the separation/pre-concentration were studied in detail, and the influences of the organic matrix P507 and the pre-ashing temperature on the determination results were also investigated. Under optimized conditions, the detection limits for La, Eu, Y and Yb were 140, 33, 35 and 29 ng L-1, respectively, and the relative standard deviations ranged from 4.5% (La) to 2.5% (Yb). The proposed method was applied to the analysis of a biological reference material (Human Hair), and the results obtained were in good agreement with the reference values.

Abstract: A method has been developed for the determination of Ca, Na, Mg, Al, Fe, Cu, Cr, Mn, and Zn in biological and clinical samples by using the FIA-ICP-AES technique. Several factors including volume of sample introduced, exposure time, and ICP operating conditions influencing the analysis were investigated. Under optimum experimental conditions, the detection limits for the analytes were 0.032-6.5 mg/mL, the relative standard deviations are in the range 0.58-2.8% (n = 10), and the recoveries of the method are higher than 90%. The results obtained show that the FIA-ICP-AES technique is superior to the method of continuous nebulization ICP-AES in analysis efficiency, precision, matrix effect, and introducing the amount of sample. This method has been applied to the analysis of a variety of biological and clinical samples.

Abstract: A new method using a microcolumn packed with nanometer TiO2 as solid-phase extractant has been developed for the simultaneous pre-concentration of trace amounts of Cu, Mn, Cr and Ni prior to their measurements by inductively coupled plasma atomic emission spectrometry (ICP-AES). Effects of pH, sample flow rate and volume, elution solution and interfering ions on the recovery of the analytes have been investigated. The adsorption capacity of nanometer TiO2 was found as 0.108, 0.149, 0.039 and 0.034 mmol g-1 for Cu, Cr, Mn and Ni, respectively. The separation of analytes can be achieved from water samples with a concentration factor of 50 times. The method has been applied for the determination of trace elements in biological sample and lake water with satisfactory results.
