摘要：In graphite furnace atomic absorption spectrometry (GFAAS) matrix modifiers have been used for enhancing sensitivity and eliminating interference. In our study, Pd and Mg(NO3)2 were used as matrix modifier, with an ashing temperature of 1400 ºC and an atomization temperature of 2400 ºC. Transversally heated pyrolitically graphite tubes, equipped with L’vov platform and Zeeman effect correction, was employed. was obtained for spiked concentrations ranging from 50 to 300 Ag obtained are comparable with those found by spectrophotometry methods for natural samples waters. Accuracy was evaluated by analyzing two Standard Reference Material at different concentration levels, a good agreement (<5%) was obtained. A series of mineral and tap waters from different parts of Spain and Morocco were analysed
