The derivatives of sulfuric acid are very many aluminum sulfate and ferrous sulfate, both of which belong to the salts of sulfuric acid products, but in fact the two are not the same but there are some similarities, so many people in the use of the two will be mixed together, let's take a look at the difference between the two sulfate some it.
1. Generally, the price of ferrous sulfate will be lower when purchased, but the effect is not very good when used, so the amount needed to achieve the same effect as aluminum sulfate is very large.
2. However, the reduction performance of ferrous sulfate is relatively good when it is used, that is, if there is some pigment dyeing in the wastewater, the substance can be used for reducing.
3. These two categories belong to the sulfate category, but the metal ions they contain are different, one of which contains aluminum ions and the other contains some divalent iron ions, so the product of aluminum ions is also white and ferrous sulfate because it contains some divalent iron ions, so the color looks yellowish green and is very easy to be oxidized.
4. There are also some differences between the two in terms of function, those containing aluminum ions can carry out deodorization work, and those with divalent iron ions can use hydrogen peroxide to do fenton treatment
5 Ferrous sulfate can also be used in aeration treatment, because the alum formed in this case is relatively small and light, and can float directly on the water after being added.
