since solid-phase and liquid-phase microextraction (spme and lpme) were introduced, as effective solvent-free methods, many efforts have been made to improve their modes and applications. however, due to limitations with sensitivity and efficiency, researchers have focused on improving the performance of their basic primary modes. in this way, in recent years, different methods such as ultrason...
Vortex-assisted surfactant-enhanced emulsification microextraction based on solidification of floating organic drop (VASEME-SFO) was used for preconcentration and speciation of antimony (ΙΙΙ, V) followed by electrothermal atomic absorption spectrometry (ETAAS). In this procedure, Triton X-114 was used as emulsifier and 1-undecanol was used as extraction solvent. This method is based on the comp...
the ultrasound assisted emulsification microextraction (usaeme) method followed byinductively coupled plasma-atomic emission spectrometry (icp-aes) was used for preconcentration anddetermination of bismuth (bi), indium (in) and lead (pb) in the plant azolla filiculoides lam. calix [4] pyrrole was used as a chelating agent and tetrachloroethylene was selected as extraction solvent. the main para...
