[Determination of aluminium in flour foods with photometric method].

OBJECTIVE
To establish a determination method for aluminium in flour foods with photometric method.


METHODS
After samples being treated with microwave digestion and wet digestion, aluminium in staple flour foods was determined by photometric method.


RESULTS
There was a good linearity of the result in the range of 0.25 - 5.0 microg/ml aluminium, r = 0.9998; limit of detection (LOD) : 2.3 ng/ml; limit of quantitation (LOQ) : 7 ng/ml.


CONCLUSION
This method of determining aluminium in flour foods is simple, rapid and reliable.
