Abstract:
ve To improve the method of determination of aluminium in water. Methods The method of aluminium chrome azurol S-cetylpyridinium bromide spectrophotometry was used. Results The improved determi-nation of aluminium revealed perfect linear relationship in determining the standard aluminium solution series at the range of 0. 0-6.0?g/25 ml aluminium. The regression equation was calculated as y = 1. 031x + 0. 008(r=0.9994) . The detection limit was 0.02 mg/L aluminium. The coefficient variation was below 4.90% . The recovery rate ranged from 93.3% to 100.0% . Conclusion The improved method was rapid and easy to operate, suitable for determination of Al3+ in a large number of water samples.
