چکیده
|
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 coexisting 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.
