摘要
9一(3,5一二溴)水杨基荧光酮(简称DBSF),是近年来合成出来的新型苯基荧光酮类显色剂,已用于钼,锡。等元素的分析、试剂在表面活性剂存在下测定锰的光度法尚未见报道.本文研究丁在CTMAB存在下,DBSF与锰的显色反应条件和光度性质。
The conditions of colour reaction of manganese with DBSAF in the presence of CTMAB were studied.In a pH=10.2 buffer solution,manganese reacts with DBSAF and CTMABto form a 1:3 complex with maximum absorption at 545 nim,the molar absorptivity is 1.6×10^(6),Beer's law is obeyed in the range of 0~9.0μg/25 ml.The method has been applied to determination of trace amounts of manganese in teas sample with satisfactory results.
