[ 1 ] - Polyelectrolyte Multilayers on Magnetic Silica as a New Sorbent for the Separation of Trace Silver in the Leaching Solutions of Antibacterial Products and Determination by Flame Atomic Absorption Spectrometry
A novel, magnetic silica sorbent with polyelectrolyte multilayers (PEMs) on its surface was prepared, and was used for Magnetic Solid Phase Extraction (MSPE) of trace A+ via Flame Atomic Absorption Spectrometry (FAAS). The experimental parameters for the MSPE procedure, such as the pH, type, and concentration of eluent, ultrasonic time and effects of co-existing ions wer...
