Pharmaceutical Drug Analysis by  Atomic Absorption Spectroscopy atomic absorption spectrophotometer atomic fluorescence spectrometer light source 1 2 type cu copper hollow cathode lampa1272
Naproxen and ibuprofen (aryl propionic acid derivatives) both are classified as non-steroidal anti-inflammatory agents. Except HPLC, no sensitive methods were reported for both the drugs. HPLC methods suffer from two drawbacks- first; requirement of costly chemicals and second; more time consuming. Because atomic absorption spectroscopy (AAS) methods are simple, sensitive, rapid, reproducible and uses low cost chemicals. The objective of present research work was to develop highly sensitive and economical analytical methods for the quantitative estimation of naproxen and ibuprofen in pharmaceutical formulations by AAS. The methods were based on the reaction of naproxen and ibuprofen with copper and cobalt chloride to form coloured metal complexes. These complexes were extracted with organic solvents and digested with acids. Naproxen and ibuprofen were indirectly estimated by AAS via the determination of the copper and cobalt content in the formed complexes. The proposed methods may be used for routine analysis of pharmaceutical formulations containing aryl propionic acid derivatives and similar pharmaceutical drugs by the analytical chemist.

A new T-shaped Graphite Furnace for Atomic Absorption Spectrometry atomic absorption spectrophotometer atomic fluorescence spectrometer light source 1 2 type cu copper hollow cathode lampa1272
This book focused on reduction of interferences in trace and ultratrace element analysis in highly interferring matrices using eletrothermal atomic absorption sepctrometery. A quick survey on interference problems accompained with the commercially available ETAAS and several developments like two step atomizers and filter furnaces to overcome these problems, then introducing the new T-shaped furnace design, principle and a new concept of high temperature chromatography with ETAAS for backgroung-Analyte signals separation to obtain more accurate absorption values.

Speciation of Certain Trace Elements in Aquatic Environment atomic absorption spectrophotometer atomic fluorescence spectrometer light source 1 2 type cu copper hollow cathode lampa1272
Two analytical techniques namely, atomic absorption spectrometry and ion chromatography were used for the total content analyses of heavy elements in water and sediments from Ismaelia canal. These elements are copper, lead, iron, nickel, cobalt, cadmium and manganese. Element speciation in natural water is important for its toxicity, bioavailability, environmental mobility and biogeochemical behavior. Ionic species of Cr(III) and the toxic Cr(VI) were separated by anion exchange ion chromatography. Total chromium in water samples is analyzed by flame atomic absorption spectrometer. Effect of pH and ionic strength of water samples on the chromatographic separation of Cr(VI) were studied. Hydride generation atomic absorption spectrometry is a highly sensitive and accurate procedure for determination of As(III) and As(V) in environmental samples. The effect of the concentration of reducing agent sodium borohydride (NaBH4), the effect of flow rate of sodium borohydride, the effect of the concentration of hydrochloric acid (HCl), the effect of the flow rate of argon gas and the effect of the sample volume on the intensity of the signal of arsenic were illustrated in the book.
