Abstract:
Objective To establish a method for the determination of aluminium in drinking water by flow injection analysis instrument.Methods In a hexamine buffer solution(pH=6.0),phenanthroline solution and ascorbic acid as the anti-interference agent,aluminium could react with chromazurol S solution and form a compound,of which maximum absorption was at 550 nm.Results The linear range for this method was 5-200 ?g/L.The correlation coefficient was 0.999 3,the detection limit of this method was 2.0 ?g/L,the recovery rates were in the range of 92.2%-108% and RSD were in the range of 2.5%-8.2%.Conclusion The flow injection method is simple,rapid,accurate and is applicable to the determination of aluminium in drinking water.
