摘要: Abstract The object of this work is to develop a simple and selective method for efficient extraction Au(III) ions in aqueous solution using new solid-phase sorbent. Polyethylenimine (PEI) ion-exchange polymer was coated on alumina the presence NaNO 3 . based sorption Au 3+ 50 mg PEI/Al 2 O A 0.5 M thiourea, then 1.0 M HCl effectively eluted gold ion aspirated into flame atomic absorption spectroscopy (FAAS). influence flow rate sample eluent, pH effect, eluent type capacity investigated. effects various diverse preconcentration separation were Relative standard deviation 4.0 μg mL −1 1.46% ( n = 10). detection limit 26.2 ng L original solution. has been applied successfully recovery trace amount from water samples.
