چکیده
Carbon active chemically bonded ethylenediamine as one sorbents successfully were applied for the enrichment of trace amount of some metal ions. The influences of the variables including pH, amount of solid phase, sample flow rate, type and condition of eluting solution and sample volume on the metal ions recoveries were investigated. The method has high sorption-preconcentration efficiency even in the presence of various other ions due to their high selectivity, while the relative standard deviation of recoveries of all understudy metal ions was found to be less than 2.8%, especially for their determination in real samples.
