摘要: Abstract A simple analytical procedure for the determination of Cu and Fe in biodiesel samples by electrothermal atomic absorption spectrometry is proposed. An aliquot sample simply mixed with tetramethylammonium hydroxide (TMAH) heated to 90 °C 5 min. Pyrolysis atomization temperatures were optimized through pyrolysis curves. The high temperature adopted, 1000 °C, certainly helped minimizing potential interferences. Even though, calibration should be carried out aqueous standard solutions presence TMAH. detection limits (3 s, n = 10), sample, quite low 15 ng g −1 24 ng g Fe, respectively. Seven samples, produced from different raw materials, including vegetable seed, frying oil animal fat analyzed. Accuracy was validated applying recovery test two enriching concentration levels (recoveries 105% 120%). precision, expressed relative deviation less than 3% 7% Fe. Copper could quantified three seven samples. fodder turnip especially rich analytes comparison other
