摘要
使用流动注射进样、多色仪分光、ＣＣＤ阵列探测器以及微机处理机等，建立了用于多组分同时测定的流动注射－ＣＣＤ阵列探测器联用分光光度装置。完成以ｍｅｓｏ－四（４－三甲铵苯基）卟啉为显色剂时铅和镉的同时测量，铅的检出限为０．０１４μｇ／ｍＬ，镉为０．０１５μｇ／ｍＬ。
A new kind of spectrophotometric instrument combined with a flow injection device,a prism spectrography,a CCD diode array detection system and a popular microcomputer was established for multi components simultaneous determination.The measurements of lead and cadmuium with meso tetra(4 trimethylammoniumphenyl)porphine were completed with the instrument.The detection limit was 0 014 μg/mL for Pb(Ⅱ) and 0 015 μg/mL for Cd(Ⅱ).The sampling rate was 60 samples/h.
