摘　　要：目的 研究并建立水产品中铝的捡测方法。方法采用干灰法对水产品进行前处理，以铬天青S分光光度法在620nm波长下比色定量。结果铝在0．5-5．0μg／25mL时，其吸光度与质量浓度之间的回归方程为y=0．104x＋0．00132，相关系数为0．9996，检出限为0．31μg，RSD为1．33～3．90％（n=6），加标回收率均为92％-104％。结论方法简便省时、灵敏稳定、干扰少、准确可靠。Objective To study and the establishment of aquatic products in the aluminum detection methods. Methods The dry ash method for preprocessing of aquatic products in order to Chrome Azurol S Spectrophotometry in the 620nm wavelength colorimetric quantification. Results In the 0.5-5.0μg/25mL Aluminum, its absorbance and the concentration of the regression equation y = 0.104x ＋0.00132, a correlation coefficient of 0.9996, the detection limit of 0.3μg, RSD of 1.33-3.90% （n = 6）, recoveries were 92%-104%. Conclusion The method is simple and time-saving, sensitive and stable, less interference, accurate and reliable.
