years food contamination, specially contamination of milk by heavy metals is considered as one of the most dangerous aspect [2].Most attention has been paid in metal residues in milk due to milk is highly consumed by infants and children [3]. The excess amount of heavy metal .

This Application Note describes the determination of aluminum in samples containing silicon dioxide using thermometric titration and EDTA as the titrant. Excess EDTA is titrated with a Cu 2+ solution of known concentration. The initial, uncomplexed Cu 2+ ions react immediately with the H 2O ₂ present in the solution, leading to a recognizable sudden increase in temperature.
