Comparison of Chemical Modifiers for the Determination of Lead in Water Samples With Electrothermal Atomic Absorption Spectrometry

Determination of lead in fish samples by slurry sampling electrothermal atomic absorption spectrometry

“…Palladium has been used as the chemical modifier to improve the signals of some volatile elements in many ETAAS applications. [19][20][21][22][23] In the following, the pyrolytic platforms of the graphite tubes were pre-treated with palladium by thermal pre-treatment. The temperature programme used for the thermal pre-treatment of the platform is given in Table 2.…”

“…The determination of phosphorus by ETAAS has never been the determination of Pb in drinking water306 and then compared a variety of chemical modifiers for the same determi-easy due to both the need to use a non-resonance absorbance line and low temperature losses of molecular phosphorus nation. 307 The conclusion of the final paper was that a combined nickel-strontium-ammonium dihydrogenphosphate species. A study of the thermal stabilization of phosphorus using sodium fluoride was performed by Hernandez et al308 chemical modifier was optimum, giving recoveries of 72-94% in natural and tap waters compared with 53-90% for other Techniques such as volatilization from dual-cavity platforms and analysis using SEM, energy dispersive X-ray spectrometry chemical modifiers such as palladium and a palladium-magnesium mixture.…”
