Estimation of Na, K, Ca, Mg, Ba, AI, Si, Pb, V, Cr, Fe, Ni, Cu and Zn in 100 samples of lube and furnace oils provided by various organizations has been successfully carried out using Atomic Absorption spectrophotometric techniques (AAS). A wet ashing, direct dilution with MIBK (Methylisobutyl Ketone) were applied for the preparation of aspiratory solutions for AAS. The results are comparable to other available techniques both in accuracy and limit of detection. The direct dilution method was abandoned in favour of wet ashing method, due to high operational cost and low reproducibility at lower level of concentration.
