摘要：

In an attempt to Improve the phenylfluorone method for determining tin, the modification of the visible spectrum of tln(IV) fluorone complex has been studied by adding cetyltrimethylammonium bromide. The band maximum observed at 530 nm for the tin(IV)-fiuorone complex does not show any bathochromic shift but the absorbance of the band maximum is significantly enhanced compared with previous methods. The tln(IV)-fluorone complex is formed at pH 1.2. The color development takes about 60 min and the color is stable for about 2 h. Beer's law is obeyed up to 3.0 µg, giving a working range of 0.20 to 3.00 µg Sn/50 mL with a standard deviation of 7.42 X 10-3. © 1978, American Chemical Society. All rights reserved.
