Quantitative Determination of Metals in Waste Aluminium Dross
Journal Title: IOSR Journal of Applied Chemistry (IOSR-JAC) - Year 2018, Vol 11, Issue 9
Abstract
Characterization of waste Aluminium dross for recovery of metal and other valuable elements are very important for secondary processing industries. Metallic impurity was determined using both classical and ICP-AES. Sample preparation plays key role in accurate quantitative determinations as it is a heterogeneous material. Different sample size (10 to 50 g) were taken for the analysis of metal and other impurities such as Fe, Ti, Ca, Mg, V, P, Cu, Mn, Na, Ni, Zn etc. The percentage of metallic Aluminium was obtained to be 20-21 % and alumina was around 70 %. In the present paper, sample preparation methodology, equipment operating condition optimization, comparative analysis using both classical and ICP-AES has been studied. Precision of measurement in the dross samples were achieved to be less than 5 % RSD.
