Solid Phase Extraction of Ultra Trace Amounts of Ni2+ by Dimethylglyoxime (DMG) Immobilized on Column
A column of alumina modified with sodium dodecyl sulfate (SDS) and dimethylglyoxime (DMG) was prepared for the preconcentration of trace nickel from water samples for flame atomic absorption spectrometry (FAAS) determinations. Under optimized conditions (pH=7.0; flow rate: 20 mlmin-1) nickel was retained on the column. The nickel collected on the column was eluted with 5 mL of 1 M nitric ac...
متن کاملDispersive Solid Phase Extraction of trace Pb(II) in water samples by New Fabricated Multi walled carbon nanotubes carboxylate
A novel, simple, sensitive and effective method has been developed for preconcentration of the trace Pb (II) ions in aqueous Samples by CNT carboxyl which in order to improve the performance of extraction and preconcentration was used. Amounting of the ions density in solution was performed by the method of flame atomic absorption spectrometry. The effective parameters on extraction such as: ef...
متن کاملReview of preconcentration and solid phase extraction for the determination of trace Lead
Spectrometric techniques for the analysis of trace lead have developed rapidly due to the increasing need for accurate measurements at extremely low levels of this element in diverse matrices. This review covers separation and preconcentration procedures, and considers the features of the application with several spectrometric techniques. The use of an appropriate sample handling technique is a...
