dc.description.abstract
A simple and fast method for determining the content of Na, K, Ca, Mg, P, and 20 heavy metals in biodiesel samples with inductively coupled plasma optical emission spectrometry (ICP OES) using a two-nozzle Flow Blurring® multinebulizer prototype and on-line internal standard calibration, are proposed. The biodiesel samples were produced from different feedstock such as sunflower, corn, soybean and grape seed oils, via a base catalyst transesterification. The analysis was carried out without any sample pretreatment. The standards and samples were introduced through one of the multinebulizer nozzles, while the aqueous solution containing yttrium as an internal standard was introduced through the second nozzle. Thus, the spectral interferences were compensated and the formation of carbon deposits on the ICP torch was prevented. The determination coefficients (R2) were greater than 0.99 for the studied analytes, in the range 0.21–14.75 mg kg−1. Short-term and long-term precisions were estimated as relative standard deviation. These were acceptable, their values being lower than 10%. The LOQ for major components such as Ca, K, Mg, Na, and P, were within a range between 4.9 ng g−1 for Mg (279.553 nm) and 531.1 ng g−1 for Na (588.995 nm), and for the other 20 minor components they were within a range between 1.1 ng g−1 for Ba (455.403 nm) and 2913.9 ng g−1 for Pb (220.353 nm). Recovery values ranged between 95% and 106%.
