RISNanometer-sized cerium oxide particles for solid phase extraction of trace amounts of mercury in real samples prior to cold vapor atomic adsorption spectrometry
سال: 2017
خلاصه:
Ceria (CeO2) nanoparticles were synthesized using the microwave-assisted heating technique and employed as a sorbent for preconcentration of trace amounts of Hg(II) ions from aqueous solutions for the first time. The ...
Preconcentration of thallium (III) and speciation of thallium (1) and (III) by single drop micro extraction using dicyclohexano-18-crown-6 and their determination by electrothermal atomic absorption spectrometry
سال: 2010
خلاصه:
Single drop micro extraction (SDME) in combination with electrothermal atomic absorption spectroscopy has been used to preconcentrate and determine thallium (III) ions followed by speciation of thallium (I) and (III). ...
