摘要
本文研究在强酸介质中 ,锡 ( )—溴代二甲氨基苯基荧光酮( BDMAF)—溴化十六烷基吡啶 ( CPB) -Tritonx-1 0 0体系的高灵敏配合显色反应 ,在强酸介质中 ,四元配合物体系的最大吸收在 550 nm,表观摩尔吸光系数为 1 .1 7× 1 0 5L mol· cm- 1,锡含量在 0～ 8μg/ 2 5m L范围内符合比耳定律 。
A Color reaction of Sn(Ⅳ) with brmopyrogallol red (BDMAF)-Tritonx-100 and cetylpyridinium bromide (CPB) has been studied spectropho tometricauy Sn(Ⅳ) forms acoordination complex with the above reagents at 2.0 mol·L -1 sulphuric acid exhibiting maximum absorption at 550nm conformed toBeer's law for Sn(Ⅳ) in the range of 0~8 μg in 25 mL with the apparent molar absorptivity of 1.17×10 5 L·mol·cm -1 . The effects of Sn(Ⅳ) are examined of Sn in pure alloysteel have been detemined.
