摘　　要：本文报道了用8-羟基喹啉-5-磺酸作荧光指示剂，采用激光-时间分辨技术进行镁、铝测定的新方法。在1～100μg／L的范围内，镁、铝的浓度和荣光强度是良好的线性关系（r＞0.999），方法的检出限分别为2μg／L和1μg／L。用标准牛肝份对方法进行了验证，并用该方法对自来水进行了直接测试。A laser-time resolved fluorimetric determination of Mg2+ and Al3+ with 8-hydroxyquinoline-5-sulphonic acid enhancer was developed. Positive linear correlation (r=0. 999) in the range of 1 to 100 mg/L was found. The detection limits of aluminium and magnesium were 1 and 2 μg/L, respectively. The method was successfully verified by the determination of Mg in bovine liver (NBS 1577a) and was further used in the tap water analysis.
