The ablation interaction between a laser and solid samples, which affects the analytical performance for laser ablation inductively coupled plasma atomic emission spectrometry (LA-ICP-AES), was studied. The emission intensities of elements observed by LA-ICP-AES (LA-ICP-AES element signal intensities) for different solid samples were measured under different laser defocusing conditions with a f...

The binding of Cu, Fe, Mn, and Zn to proteins in blood and in blood fractions was investigated, since their interactions in free radical metabolism in humans is of great interest. An HPLC-ICP-AES technique was developed allowing adequate separation of metalloproteins and of inorganic and organic metal species. For the separation of metalloproteins in erythrocytes and blood plasma a Merck Superf...

the dispersive liquid–liquid microextraction (dllme) method for determination of pb +2 and cd +2 ions in the environmental water samples was combined with inductively coupled plasma-atomic emission spectrometry (icp-aes). ammonium pyrrolidine dithiocarbamate (apdc), chloroform and ethanol were used as chelating agent, extraction solvent and disperser solvent, respectively. some effective parame...

Mineral content of food in general, and of meat and meat products in particular, has been widely studied mainly due to its essential role in human nutrition and implication on safeness issues, i.e., mineral toxicity and deficiencies. Furthermore, since a few decades ago, instrumental analytical techniques based on atomic absorption or emission spectrometry applied to the determination of the mi...

This work compares efficiencies of pneumatic and ultrasonic nebulizers and discusses drawbacks observed in trace element analyses of environmental matrices using ICP-AES with ultrasonic nebulization. The interference observed is mainly due to variable calcium content in samples; in most cases the excessive plasma loading by Ca is responsible for signal suppression of analyte elements. Such matr...

In this study, tablets coming from different police seizures (in Switzerland) were analysed by ICP/MS and ICP/AES. Two methods of preparation were carried out in order to compare the influence of sample preparation. 25 elements were screened by ICP/AES whereas most of the periodic table could be screened by ICP/MS. Approximative detection limits were determined for most of the elements showing,...

Sodium aluminosilicate scaling in evaporators during alkali recovery is often associated with the concentration of aluminum and silicon in black liquor. The scaling problems are widespread during the utilization of nonwood raw materials. This study established a fast, reliable, and precise method to determine the aluminum concentration in bamboo black liquor by inductively coupled plasma-atomic...

An inductively coupled plasma atomic emission spectrometry (ICP-AES) method was developed for the determination of phosphorus in fertilizers. Total phosphorus, direct extraction available phosphorus (EDTA), and water-soluble phosphorus, reported as phosphorus pentoxide (P205), in 15 Magruder check fertilizers were measured by ICP-AES, and the results were compared with those obtained by the AOA...
