Effervescence-assisted liquid phase microextraction prior to slotted quartz tube-flame atomic absorption spectrometry for cadmium determination in domestic wastewater samples

Autor: Tülay Borahan, Sezgin Bakırdere, Özlem Yağci, Nazime Ebrar Karlıdağ

Publikováno v: Chemical Papers. 75:6307-6314

This paper describes an effervescence-assisted liquid phase microextraction (EA-LPME) method coupled to the SQT-FAAS system for determining trace levels of cadmium in domestic wastewater samples. Preconcentration of the cadmium ions was carried out b
