Determination of Cadmium in Environmental Sample by Electrochemical Hydride Generation Electrothermal Atomic Absorption with in Situ Trapping in Graphite Tube Atomizer
A homemade batch electrolytic cell with a Sn-Pb alloy cathode used to generate cadmium hydride. Several parameters influencing the electrochemical hydride generation and trapping on the coated graphite tubes, and atomization process have been investigated. Ir-, W-, and Zrcoated graphite tubes were used for trapping cadmium hydride. It was found that Ir-coated graphite provided the best sensitiv...
متن کاملInterferences in the quartz tube atomizer during arsenic and antimony determination by hydride generation atomic absorption spectrometry
Interferences of some metals in the determination of arsenic by hydride generation atomic absorption spectrometry utilizing a quartz tube atomizer were studied. The atomizers were coated under vacuum with Ni, Au, Pd and Cr. The arsenic signal was almost totally suppressed by all the metal coatings and thus the interferences from metal ions in the determination of arsenic were attributed both to...
متن کاملDetermination of cadmium in wine by electrothermal atomic absorption spectrometry.
A method is described for direct electrothermal atomic absorption spectrometric (ETAAS) determination of cadmium in untreated samples of wine. Pyrolytic graphite tubes and graphite tubes with standard L'vov pyrolytic platforms were tested as atomizers. The detection limit achieved was 0.08 microg L(-1) Cd in wine. The relative standard deviation for the concentration range from 0.2 to 10 microg...
متن کاملAluminum determined in plasma and urine by atomic absorption spectroscopy with a transversely heated graphite atomizer furnace.
We compared a stabilized-temperature L'vov platform furnace containing an end-heated graphite atomizer (HGA) and transverse Zeeman background-correction system with a side-heated furnace system (transversely heated graphite atomizer; THGA) containing a longitudinal Zeeman background-correction system for the determination of aluminum in plasma and urine. The regression statistics for the correl...
متن کاملDetermination of lead and cadmium in water samples by cloud point extraction prior to flame atomic absorption spectrometry determination
Pb and Cd in water samples were determined by cloud point extraction (CPE) with sodiumdiethyldithiocarbamate (DDTC) as the chelating agent and octylphenoxypolyethanl (Triton X-114) asthe surfactant prior to flame atomic absorption spectrometry (FAAS) determination. The main factorsof affecting the extraction and detection processes were optimized. The preconcentration of 10 mL ofstandard soluti...
