What is the reason for activated carbon during crystallization ? Why is recommended to use little and a lot during this process
Activated carbon is often used during crystallization processes because of its ability to adsorb impurities from the solution being crystallized. The activated carbon has a high surface area and a network of small pores, which allows it to attract and trap various organic and inorganic contaminants present in the solution.
Using a little amount of activated carbon during crystallization helps to remove a moderate level of impurities from the solution. This can be suitable when the impurities do not significantly affect the quality of the final product or when the solution is not highly contaminated.
On the other hand, using a large amount of activated carbon during crystallization is recommended when the solution is heavily contaminated or when the impurities have a strong impact on the quality of the crystals. The increased amount of activated carbon provides more surface area for adsorption, allowing for a more thorough removal of impurities from the solution.
Ultimately, the decision on whether to use a little or a lot of activated carbon during crystallization depends on the degree of contamination and the desired level of purity for the final crystals.
