ABSTRACT
Objective To establish a method for determination of aluminum in water by graphite furnace atomic absorption spectrometry (GFAAS). Methods Aluminum in water was directly determined by GFAAS at wavelength of 394.4 nm without any matrix modifiers. Results A good linearity (r=0.999 5) was obtained, the linear range was 0-0.600 mg/L. RSD of samples ranged from 2.1% to 6.4%, the average rates of recovery were between 91.0%-108.0%. The detection limit of the method was 0.6 ?g/L, the quantitative limit was 1.9 ?g/L. There was no significant difference between the results determined at wavelength of 394.4 nm and 309.3 nm. Conclusion This method is simple, rapid, accurate and has a wide linear range. It can be applied in the determination of aluminum in drinking water.
