The method showed good precision (RSD(%) 40 mcg/dl). Samples were acidified (0.5% (v/v) nitric acid), and the standard addition method was used for the sequential determination of the analytes in diluted samples (1:2). The main absorption lines were used for all the elements, and the number of selected analytical pixels were 5 (CPÂ☒) for Cd, Cu, Fe, Ni, Pb and Zn, and 3 pixels for Mn (CPÂ☑).

Module SFS 6 for sample injection was used in the manual mode, and flame operating conditions were selected. The objective of this work is to develop a method for the determination of metals in saline matrices using high-resolution continuum source flame atomic absorption spectrometry ( HR-CS FAAS). Use of High-Resolution Continuum Source Flame Atomic Absorption Spectrometry ( HR-CS FAAS) for Sequential Multi-Element Determination of Metals in Seawater and Wastewater Samples Correlation coefficients of calibration curves built up by plotting A(Pb)/A(Bi)versus Pb concentration were higher than 0.9953 (FAAS) and higher than 0.9993 (GFAAS). Analysis of samples containing different matrices indicated close relationship between Pb and Bi absorbances. The developed procedure was successfully applied to water samples.īismuth as a general internal standard for lead in atomic absorption spectrometry.īechlin, Marcos A Fortunato, Felipe M Ferreira, Edilene C Gomes Neto, JosÃ© A NÃ³brega, Joaquim A Donati, George L Jones, Bradley Tīismuth was evaluated as internal standard for Pb determination by line source flame atomic absorption spectrometry (LS FAAS), high-resolution continuum source flame atomic absorption spectrometry ( HR-CS FAAS) and line source graphite furnace atomic absorption spectrometry (LS GFAAS). The accuracy of the procedure was confirmed by analyzing certified materials (NIST SRM 1643e, Trace elements in water) and spiked real samples. Under the optimal conditions, limit of detection obtained with HR-CS FAAS and Line Source FAAS (LS-FAAS) were 0.49Â Î¼gÂ L(-1) and 3.91Â Î¼gÂ L(-1), respectively. The adsorbed aluminum on resin was eluted with 5Â mL of 2Â molÂ L(-1) HNO(3) and its concentration was determined by high-resolution continuum source flame atomic absorption spectrometry ( HR-CS FAAS). Sample solution pH, sample volume, flow rate of sample solution, volume, and concentration of eluent for solid-phase extraction of Al chelates with 4- benzoic acid on polymeric resin (Duolite XAD-761) have been investigated. In the present study, a separation/preconcentration procedure for determination of aluminum in water samples has been developed by using a new atomic absorption spectrometer concept with a high-intensity xenon short-arc lamp as continuum radiation source, a high-resolution double-echelle monochromator, and a charge-coupled device array detector. Melt has occurred just keeping it contained now.Solid-phase extraction and separation procedure for trace aluminum in water samples and its determination by high-resolution continuum source flame atomic absorption spectrometry ( HR-CS FAAS). This is accounting for the increased radiation around the plant. Containment pressure is probably high and is being released to prevent primary containment breach.

Hopefully the thicker primary containment building is intact and will hold most of the core material now called corium (molten core mass). That means the hydrogen has leaked past the primary containment structure and reached its explosive range in the secondary containment. The report I heard mentioned that it was the outer containment that exploded. This is an exothermic reaction that produces even more heat than the decay heat. Fuel cladding material when it melts reacts to produce hydrogen. It means the zirc-water reaction has already occurred. If this was a hydrogen explosion like one report said.

I am in this line of work and have been piecing together all the information and video. It is now about containment and that may be lost soon.
