Development of a method to determine Ni and Cd in biodiesel by graphite furnace atomic absorption spectrometry

Fuel, 2011

This paper proposes a low cost, simple, fast method for determining Ni and Cd in biodiesel samples by graphite furnace atomic absorption spectrometry (GFAAS). The method was evaluated in biodiesel from different sources. Tungsten was used as a permanent modifier and the samples were prepared in the form of microemulsions, by mixing about 0.5g of biodiesel with 5g of surfactant
