印度 Prakash 等报导了对甲氧基苯甲醛-4-苯基-3-缩氨基硫脲(Apt)的合成、吸收光谱特性及其在分析中的应用。在盐酸—醋酸钠缓冲溶液中(pH1.7—3.0)Pt与Apt 生成黄色络合物的显色反应为基础、建立了一个简单、快速、有选择性和灵敏的测定铂的分光光度法、络合物的形成反应在1分钟内完成,最大吸收波长在360nm,Pt-Apt 络合比为1∶2。为了使 Pt 全部形成络合 India Prakash et al. Reported the synthesis of p-methoxybenzaldehyde-4-phenyl-3-thiosemicarbazone (Apt), its absorption spectra and its applications in analysis. A simple, rapid, selective and sensitive method for the determination of platinum was established based on the color reaction of Pt with Apt to form yellow complex in hydrochloric acid-sodium acetate buffer solution (pH 1.7-3.0) The complex formation reaction was completed in 1 minute, the maximum absorption wavelength was at 360 nm and the Pt-Apt complex ratio was 1: 2. In order to make all of Pt complex
