This method was developed for the determination of trace amounts of aluminum(III) in dialysis concentrates using atomic absorption spectrometry after coprecipitation with lanthanum phosfate. The analytical parameters that influenced the quantitave coprecipitation of analyte including amount of lanthanum, amount of phosfate, pH and duration time were optimized. The % recoveries of the analyte io...

Introduction: This study covered the assessment of the natural radioactivity levels and heavy metalsconcentration in dust samples collected from selected schools in the holy Governorate of Karbala. The purpose of thisstudy was to assess the radiological health and safety impact of dust pollution on the children going to school. Material and Methods:</...

a chelating resin of polystyrene divinylbenzene resin functionalized by 1-(2-pyridylazo) 2- naphtol (psdvb-pan) has been synthesized and its sorption properties have been investigated for preconcentration and determination of cadmium at μg/l level by flame atomic absorption spectrometry. the procedure is based on the sorption of cd(ii) ions on a minicolumn of synthesized chelating resin. the...

a new and simple method followed by atomic absorption spectrometry has been developedfor indirect determination of ascorbic acid (aa). the proposed method was based on the oxidationof aa to dehydroascorbic acid with cu2+cation(200mgl-1)in an ammonium thiocyanatesolution atph2.4. aa reduces cu2+to cu+followed by the precipitation of cu+ with scn-. then, the excess ofcu2+in the solution was measu...

some heavy metals are dangerous to health and there is rising concern about the quality of foodstuffs in some parts of the world. fish, particularly tuna fish, can concentrate huge quantities of several metals from water and they even play a significant role in human nourishment. objectives: in this study, the concentrations of mercury and four trace metals in five brands of canned tuna samples...

toxic heavy metals, such as lead (pb) and cadmium (cd) are widely used in industry and their accumulation in the living tissues may cause serious health problems and ecological hazards. twenty four moderately halophilic bacteria isolated from saline environments of iran were used to study their ability to bioremediation of lead and cadmium. amongst them, a gram-negative rod shaped bacterium, de...

This study aims to investigate the content of lead in most frequently used brands of cosmetics products in Morocco.100 samples of kohl (kohl powder, galena, eye pencils and paste) were selected taken from large cosmetic stores in Morocco. And lead of them is analyzed using a Fast Sequential Atomic Absorption Spectrometer (SAAFS 240).The results showed that the concentrations of lead in kohl sam...
