Cold vapour atomic fluorescence determination of mercury in milk by slurry sampling using multicommutation
A highly sensitive mechanized method has been developed for the determination of mercury in milk by atomic fluorescence spectrometry (AFS). Samples were sonicated for 10 min in an ultrasound water bath in the presence of 8% (v/v) aqua regia, 2% (v/v) antifoam A and 1% (m/v) hydroxilamine hydrochloride, and after that, they were treated with 8 mmol l−1 KBr and 1.6 mmol l−1 KBrO3 in an hydrochlor...
متن کاملSlurry Sampling for Arsenic Determination in Sediments by Hydride Generation Atomic Absorption Spectrometry
Um método simples e robusto para a determinação de arsênio em sedimentos por espectrometria de absorção atômica com geração de hidreto (HG-AAS) usando a amostragem em suspensão é proposto. Água régia (5% v/v) e ácido fluorídrico (1% v/v) foram misturados a uma alíquota do sedimento com tamanho de partícula 50 μm e colocados no banho ultrasônico por 30 min. A suspensão foi deixada em repouso por...
متن کاملDetermination of lead in fish samples by slurry sampling electrothermal atomic absorption spectrometry.
Ultrasonic slurry sampling electrothermal atomic absorption spectrometry (USS-ETAAS) was been applied to the determination of lead in several fish samples. The influences of instrument operating conditions and slurry preparation on the signal were examined. Palladium and ammonium nitrate were used as the modifier to improve the signal. Since the sensitivity to lead in various fish slurries and ...
متن کاملDetermination of Metal Loading in Heterogeneous Catalyst by Slurry Sampling Flame Atomic Absorption Spectrometry
Quantification of metal loading in supported catalysts is imperative; however, the analytical methods are usually time-consuming, expensive, and require sophisticated equipment and sample extraction with hazardous and corrosive strong acids. Herein, we report a new method for quantification of metal in supported catalysts using slurry sampling flame atomic absorption spectrometry. The slurry sa...
متن کاملA modified method for the determination of organic mercury in biota [great cormorants (phalacrocorax carbo)] by advanced mercury analyzer
Background: Contagion of aquatic ecosystems to heavy metals especially mercury (Hg) has risen concerns about healthiness of marine organisms. Organic mercury compounds are highly toxic for animals, and its detection in various samples is frequently needed. In present study we have described a new method for measurement of organic mercury and total mercury concentration in great cormorants (ph...
