Trace-metal analysis with separation methods
This broad overview covers the use of gas and liquid chromatography as well as capillary electrophoresis for the determination of metal ions and metalcontaining species, such as organometallic compounds or metalloproteins. We pay particular attention to the latest developments and consider the features of the various detection techniques and applications of the different methods. a 2005 Elsevie...
متن کاملChelation of Trace Metals in Nutrient Solutions.
Plant nutrition studies frequently require nearly complete elimination of trace metals from the nutrient media in which the plants are to be grown. Conventional methods of purification by recrystallization and precipitation have been used for this purpose in some studies. These have proved more difficult and less effective than the adsorption technique developed by STEINBERG (11) and improved b...
متن کاملAlkaline phosphatase activity in the subtropical ocean: insights from nutrient, dust and trace metal addition experiments
*Correspondence: Claire Mahaffey, Department of Earth, Ocean and Ecological Sciences, University of Liverpool, Nicholson Building, 4 Brownlow Street, Liverpool, Merseyside L69 3GP, UK e-mail: [email protected] Phosphorus is an essential nutrient for all life on earth. In the ocean, the most bioavailable form of phosphorus is inorganic phosphate, but in the extensive subtropical gyres, phosphat...
متن کاملChromosome replication in Caulobacter crescentus growing in a nutrient broth.
The pattern of chromosome replication in the Caulobacter crescentus cell cycle was studied by examining the rate of deoxyribonucleic acid (DNA) synthesis during synchronous growth in a fast-growth nutrient broth. As reported previously for the cell cycle in a slow-growth minimal medium (Degnen and Newton, 1972), the Caulobacter cell cycle (at the fastest available growth rate) in nutrient broth...
متن کاملTrace metal analysis by laser-enhanced ionization in flames.
We review atomic flame spectrometry of metals based on the selective laser-enhancement of the rate of atomic ionization. A discussion of basic principles, prior literature, and instrumentation is followed by an overview of analytical figures of merit for the technique, and a look at its present status and areas for future development.
