| چکیده انگلیسی مقاله |
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 were investigated. The detection limit of the developed method was 0.17 ng/mL for Ag+ with an enrichment factor of 35. This method was also successfully applied to the determination of trace Ag+ in the leaching solution of different antibacterial products with satisfactory results. |
