A novel method for determination of aluminum in aquatic products was developed in the paper. The sample was dissolved with microwave digestion and determined by spectrophotometry on wave length 620 nm. In the 0.5~6.0 μg/25 mL, Aluminm its absorbance and concentration of the regression equation y=0.146x+0.0071, a correlation coefficient of 0.9996, the detection limit of 0.3μg. RSD of 1.31%~3.11%, recoveries were 94.7%~97.0%. Condusion, the mesthod is simple, sensitive and stable, accurate and reliable.
