Abstract
Several variables such as sample and reagents volumes, flow rates and reagent concentrations were investigated in detail. A linear calibration graph was obtained for arsenic determination between 0.1 and 3 μg lâ1. The detection limit of the proposed technique (3Ïb/S) was 0.05 μg lâ1. The relative standard deviation (R.S.D.) of As at 1 μg lâ1 was 4.4 % (n = 15). A sample throughput of 10 samples per hour was achieved. This technique was validated by means of reference solid and water materials with good agreement with the certified values. Satisfactory results for speciation of As(III) and As(V) by means of the developed technique were obtained.
