Abstract
A column of alumina modified with sodium dodecyl sulfate (SDS) and dimethylglyoxime (DMG) was prepared for the preconcentration of trace nickel from water samples for flame atomic absorption spectrometry (FAAS) determinations. Under optimized conditions (pH=7.0; flow rate: 20 mlmin-1) nickel was retained on the column. The nickel collected on the column was eluted with 5 mL of 1 M nitric acid. Recovery was greater than 98%. A concentration factor of 200 can be achieved by passing 1000mL of sample through the column. The relative standard deviation (10 replicate analyses) at the 200 ngml-1 level for nickel was 2.2% and the corresponding limit of detection (based on 3σ) was 0.82 ngml-1. The method was applied to the determination of nickel in row solution for nickel plating.
