| Abstract: | Objective Explores the graphite furnace for direct determination of lead in sea water by ammonium nitrate detection method. Method Dilution of seawater samples, using palladium nitrate and ammonium hydrogen phosphate two as matrix modifier. The content of lead in sea water was determined by graphite furnace -atomic absorption spectrometry （GFAAS）. Result Compared with GB method, this method has the advantages of simple operation fast and does not contact the toxic organic solvent. According to the use of the new test method for the determination of seawater samples with national standard method for the determination of results, and through the recovery of the validation, the result is accurate and reliable. Conclusion This method is suitable for the determination of lead content. |
