    The pure solid crystals are then separated from the remaining liquor by filtration or centrifugation. Recrystallization : In analytical and synthetic chemistry work, purchased reagents of doubtful purity may be recrystallised, e.g. dissolved in a very pure solvent, and then crystallized, and the crystals recovered, in order to improve and/or ...

    en.wikipedia.org/wiki/Water_of_crystallization

    Classically, "water of crystallization" refers to water that is found in the crystalline framework of a metal complex or a salt, which is not directly bonded to the metal cation. Upon crystallization from water, or water-containing solvents , many compounds incorporate water molecules in their crystalline frameworks.

    For better water purification or treatment processes nanotechnology is preferred. Many different types of nanomaterials or nanoparticles are used in water treatment processes. Nanotechnology is useful in regards to remediation, desalination, filtration, purification and water treatment.

  6. Hydrothermal synthesis - Wikipedia

    en.wikipedia.org/wiki/Hydrothermal_synthesis

    Hydrothermal synthesis can be defined as a method of synthesis of single crystals that depends on the solubility of minerals in hot water under high pressure. The crystal growth is performed in an apparatus consisting of a steel pressure vessel called an autoclave, in which a nutrient is supplied along with water. A temperature gradient is ...
