FAAS Determination of Au and Pd After Selective Preconcentration on Ethylenediamine Silica Material Prepared By the Sol-Gel Method

Atomic spectrometry update. Environmental analysis

“…Silica modied with ethylenediamine, prepared using the sol-gel technique, was also employed to preconcentrate Au and Pd from a platinum ore RM. 355 A procedure for the separation of Pt from ferrous matrices was based on the sorption of Pt as chloride complexes on polyurethane foam, prior to determination by ICP-AES. 356 Measurement LODs in solution were 66 mm L À1 and the precision 1.2% RSD (n ¼ 10).…”

Column Solid Phase Extraction of Ni(II) and Cu(II) Using Salicylaldehyde-Modified Polyamine Polyurea Resin for Their Determination by FAAS in Waters

“…Several techniques have been used for the determination of metal levels, such as capillary electrophoresis (CE) (3), electrothermal atomic absorption spectrometry (ETAAS) (4), microwave plasma-atomic emission spectrometry (MP-AES) (5), anodic and cathodic stripping voltammetry (ASV-CSV) (6), inductively coupled plasma mass spectrometry and inductively coupled plasma-optical emission spectroscopy (ICP-MS and ICP-OES) (7,8), and flame atomic absorption spectrometry (FAAS) (9)(10)(11). Each technique has its advantages and disadvantages.…”

Preconcentration of trace gold and silver on titanium dioxide nanotubes and their determination by inductively coupled plasma mass spectrometry

“…Due to their rare occurrence, high economic value and attractive chemical and physical properties, Au and Ag have many applications in industry, jewelry and biomedicine. [1][2][3][4] In particular, recent advances in nanotechnology have rapidly increased the usage of gold and silver in consumer products, ranging from medicine, socks, paints, bandages, food containers and even food supplements. [5][6][7] Usage and disposal of these products likely result in their release into the environment.…”
