2-pyridinecarbaldehyde-5-nitro-pyridylhydrazone (2PC-5NPH) was synthesized and its application in the spectrofluorimetric determination of Fe(III) ions in the presence of surfactants was examined. An emission peak of 2PC-5NPH, which increased remarkably by the addition of Fe(III), occurs at 420 nm upon excitation at 300 nm, and allows for the sensitive, selective determination of the ferric ion in the 0.20-1.45 mug ml(-1) range. The detection limit is 0.028 mug ml(-1) in the presence of hexadecyltrimethylammonium bromide (CTMAB).
合成了2-吡啶甲醛-5-硝基吡啶腙（2PC-5NPH），并研究了其在表面活性剂存在下用于荧光光谱法测定铁（III）离子的应用。2PC-5NPH在300nm激发下于420nm处出现发射峰，加入Fe(III)后该峰显著增强，可用于灵敏、选择性地测定0.20 - 1.45μg ml⁻¹范围内的铁离子。在十六烷基三甲基溴化铵（CTMAB）存在下，检测限为0.028μg ml⁻¹。
