Selective Separation and Preconcentration of trace Amounts of Gallium in Water and Rice Samples using Cloud Point Extraction and Determination by Inductively Coupled Plasma-Atomic Emission Spectrometry
In the present study a cloud-point extraction process using non-ionic surfactant Triton X-114 for selective extraction of gallium from aqueous solutions was developed. The method is based on the complex formation of Ga (III) with N, N′ -bis (salycilidene)-1, 2-phenylenediamine (salophen) as a chelating agent in buffer media of pH 5. After phase separation and dilution of the surfactant-rich pha...
متن کاملPrimary speciation analysis of metal trace elements in Radix Scutellariae using inductively coupled plasma-mass spectrometry
Radix Scutellariae from different producing areas were processed by wet digestion, and a total of 28 metal trace elements, which may be essential or harmful to human being, were determined using inductively coupled plasma-mass spectrometry (ICP-MS) firstly. The results indicate that the kind of metal elements in Radix Scutellariae from different area were basically the same, but the contents ma...
متن کاملDetermination of trace elements in marine plankton by inductively coupled plasma mass spectrometry (ICP-MS).
A method has been developed for the determination of 23 elements in marine plankton in which inductively coupled plasma (ICP) source mass spectrometry (MS) was used to quantify the elements in the solution after digestion in a mixture of hydrofluoric and nitric acids in sealed PTFE vessels in a microwave field. The procedure was validated by the analysis of a standard reference soil (SRM 2709 S...
متن کاملScreening trace elements and electrolytes in serum by inductively-coupled plasma emission spectrometry.
This rapid, accurate procedure for trace elements and electrolytes in serum requires little sample preparation: to 1 mL of serum a single reagent is added that contains trichloroacetic and hydrochloric acids for protein precipitation, hydroxylamine sulfate for iron reduction, and yttrium as the internal standard. After centrifugation, the supernates are directly analyzed for Na, K, Mg, Ca, Pi, ...
