The authors found that pure aluminium foil and a small piece of Al-Fe mother alloy con- raining large amount of Fe, were easily dissolved in sulfuric acid of suitable concentration, and established a rapid volumetric method of determination of iron in aluminium foil and Al- Fe mother alloy by decomposition with sulfuric acid. By this method the iron in sample can be dissolved in H2SO4 as Fe2+ without using any reducing reagent.The presence of a micro-amount of Ti and V are found to prevent disturbing.The presence of Cu is harmful but it can be removed by filtration.The procedure of this method can be carried out in 10-20 minutes, its manipulation and apparatus are simple, the cost is low, and it provides precise result.
