Influence of Phosphorus and Calcium on Flame Atomic Absorption Spectrophotometric Determination of Lead in Canned Fish Products
Keyword(s):
Abstract Lead was determined in the presence of whole multiples of the P/Ca ratio found in Portuguese canned fish by flame atomic absorption spectrophotometry with and without using an ashing aid. Under our experimental conditions, use of the ashing aid eliminates P and Ca interference. Results with real samples, spiked with 1, 2,3, and 4 ppm lead, are presented and statistically treated.
