Abstract EN
An efficient method for preconcentration of trace amounts of Mn (II) and Ni (II) ions by using a minicolumn (10 mm × 30 mm i.d.) filled with a diimine derivative Schiff base on silica-gel has been reported.
The retained analytes on the column were recovered with 5 mL of mixture of nitric acid 5 mol L−1 and methanol (1 : 1) and were determined by a flame atomic absorption spectrometer.
Different factors including pH of sample solution, sample volume, amount of sorbent, eluent volume, and interference of other ions have been studied and the optimized conditions developed were utilized for the trace determination of Mn (II) and Ni (II) in natural water samples.
The recoveries for the analytes under the optimum working conditions were higher than 98%.
The relative standard deviations of the determinations (10 replicate analyses) at 25 μg L−1 of Mn (II) and Ni (II) were 2.5% and 2.3%, respectively.
The limit of the detection (3s, n=10) for analytes were found to be 0.20 μg L−1 for Mn (II) and 0.15 μg L−1 for Ni (II).
The proposed method was applied to the analysis of natural water samples with satisfactory results.
