ABSTRACT

Objective:

To establish an atomic absorption spectrometry method for the determination of lead and ferrum in pre-mix-ture coating film.

Methods:

The samples were digested by microwave digestion system, and Pb was determined by graphite atomic ab-sorption spectrometry(GFAAS), and Fe was determined by flame atomic absorption spectrometry(FAAS).

Results:

There was good linear relationship within the range of 1.0-5.0 μg·L-1(r=0.999 4) for lead and 0.1-1.0 mg·L-1(r=0.998 4) for ferrum. The recovery of lead was 91. 3%(RSD=1. 4%,n=9)and that of ferrum was 89. 9%(RSD=3. 5%,n=9).

Conclusion:

The method is accurate and stable, which can be used for the determination of lead and ferrum in pre-mixture coating film
