In this letter a preliminary study of the influence of chloride matrices on lead was described. HITACHI Model 180-50 atomic absorption spectrometry and cup cuvette were used. Pb 283.3 nm was used for measurement. Lead hollow cathode lamp was operated at 7.5mA. All absorbance-time curves were obtained under the following graphite atomizer program, as indicated by the temperature and time displaying on the CRT screen: dry, 80—120℃ (30s); ash, 400~℃ (30s); atomize, 2000℃ (7s); and clean, 2400℃ (3s). Aqueous test solution of lead was taken as the nitrate, and aqueous matrix solu-
