Both at the same time added, so that the iron content reduced from 25ppm to 8ppm, while silicon content reduced from 32ppm to 10ppm, purify aluminum isopropoxide is about 99.997% purity.

When you add 2, so that the iron content of 25 ppm to 8 ppm of silicon content, while the 32 ppm to 10 ppm, with the exception of isopropyl alcohol, aluminum is approximately 99.997 % purity.

When the two simultaneously increase, causes hard the content to reduce by 25ppm is 8ppm, simultaneously the silicon content reduces by 32ppm is 10ppm, after mixed the aluminium isopropoxide purity is approximately 99.997%.

Both added at the same time, the iron content is 25ppm down to 8ppm, and Silicon content by the 32ppm lower 10ppm after removal of isopropyl alcohol purity of aluminum is about 99.997%.
