Determination of major antimony species in seawater by continuous flow injection hydride generation atomic absorption spectrometry

H-point standard addition method applied to simultaneous kinetic determination of antimony(III) and antimony(V) by adsorptive linear sweep voltammetry

“…Techniques such as atomic absorption spectrometry [5,6], plasma emission spectroscopy [7], inductively coupled plasmamass spectrometry [8], neutron activation analysis [9], chromatography techniques [10,11], atomic absorption spectrometry with hydride generation [12][13][14][15] and spectrophotometry [16][17][18] have been applied for the speciation of antimony. However, some of these methods are not sufficiently selective or sensitive and some of these involve various long procedures.…”

Determination of Trace Metals in Waste Water and Their Removal Processes

“…Cabon and Madec determined antimony in sea water samples by continuous flow injection hydride generation atomic absorption spectrometry. After continuous flow injection hydride generation and collection onto a graphite tube coated with iridium, antimony was determined by graphite furnace atomic absorption spectrometry [28]. Yersel et al developed a seperation method with a synthetic zeolite (mordenite) was developed in order to eliminate the gas phase interference of Sb(III) on As(III) during quartz furnace hydride generation atomic absorption spectrometric determination [29].…”

Direct Determination of Trace Antimony in Natural Waters by Photochemical Vapor Generation ICPMS: Method Optimization and Comparison of Quantitation Strategies

“…This requirement leads to relatively lengthy analytical protocols and increases the possibility of sample contamination. 16,17 An underestimation of the total Sb concentration may still occur since natural waters may contain organic forms of Sb which cannot be decomposed using a prereduction approach typical of CHG. Furthermore, use of unstable KBH 4 /NaBH 4 and the high concentration of HCl required for efficient CHG of Sb(V) are not favorable; greener, simpler, and more cost-effective sample preparation techniques are needed.…”

“…17 In addition, the risk of sample contamination is lower, and improved limits of detection (LODs) can be achieved due to the lower blank levels. 16,17 Use of UV irradiation alone or in combination with other chemical oxidants has been proposed for online photodecomposition of numerous species of several elements which serve to enhance analytical sensitivity 16,18 when coupled to ICPMS. Using a high-efficiency photooxidation reactor as a source of vacuum ultraviolet light at 185 nm provides efficient irradiation; organoarsenic species can be converted to As(V) within 3.5 s online without addition of any chemical oxidants.…”
