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。
Flow injection injection, multicolor spectrophotometer, CCD array detector and computer processor were used to establish a flow-injection-CCD array detector combined spectrophotometer for simultaneous determination of multiple components. The simultaneous determination of lead and cadmium with meso-tetrakis (4-trimethylammoniunophenyl) porphyrin was achieved. The detection limit of lead was 0.014μg / mL and that of cadmium was 0.015μg / mL.
