摘要
研究了在溴化十六烷基三甲胺（ＣＴＭＡＢ）的存在下，氨－氯化铵缓冲溶液（ｐＨ１０）中，铝与水杨基荧光酮（ＳＡＦ）的显色反应。λｍａｘ＝５５６ｎｍ，线性范围０～５μｇ／（２５ｍＬ）。本方法用于食品中铝的测定，回收率为９８％～１０４％。
The color reaction between aluminium and SAF in ammonia-ammonium chloride buffer with CTMAB was studied.λ max was 556 nm.The linear rage was 0～5 μg/25 mL.Using this method to determine the quantity of aluminium in food,the rate of recovery was 98%～104%.
