摘要
A method for nickel preconcentration by coprecipitation using Al(OH)(3), followed by centrifugation and dissolution with HNO3 prior to a determination by flame atomic absorption spectrometry (FAAS), was investigated. Preconcentration factors of 30 and 200 were tested, and the detection limit (3 x sd/m, n = 10) was 0.05 mu g L-1. The method was applied to real samples, and the results agreed with those obtained directly by graphite furnace atomic absorption spectrophotometry.
