Zini提出了灵敏的荧光光度法,其基础是Al与媒染黑-17染料在正丙醇中形成络合物的溶液与乙酸-乙酸钠缓冲溶液(pH4.8)混合后,在40℃保持60min。然后在E_x=565nm,E_m=610nm测定荧光强度。在0—60ng/ml的铝浓度范围内工作曲线呈线性。标准偏差σ=1.5,铝的检测限是3ng/ml。
Zini proposed a sensitive fluorimetric method based on the mixing of a solution of Al complexed with mordant Black-17 dye in n-propanol with an acetic acid-sodium acetate buffer solution (pH 4.8) at 40 ° C for 60 min . Fluorescence intensity was then measured at E_x = 565 nm, E_m = 610 nm. The working curve is linear over the aluminum concentration range of 0-60 ng / ml. Standard deviation σ = 1.5, the detection limit of aluminum is 3ng / ml.
