Recrystallization: Solid–Solution Equilibria

1.0K
Recrystallization is a purification technique used to separate impurities from solid compounds. In this technique, no chemical reactions occur. Instead, it exploits physical properties only, specifically, the solubility differences between the desired compound and impurities, either at a single temperature or at different temperatures, and under other selected conditions. The solid-solution equilibrium (solubility equilibrium) of each component in the solution represents a binary phase...

Crystal Growth: Principles of Crystallization

1.4K
Crystallization is a phase transformation process in which crystals are precipitated from a supersaturated solution or formed from other sources. During crystallization, atoms or molecules arrange themselves into a well-defined, rigid crystal lattice to minimize energy.
Initiating crystallization involves manipulating the concentration of the solute and the temperature of the solution. Since crystal growth occurs when the ratio of concentration and solubility of the solute in the solvent...

Precipitation Processes

345
The experimental conditions in a gravimetric analysis should be optimized to maximize the particle size and purity of the obtained precipitate. Ideally, the concentration of the precipitating reagent should be low with effective stirring to maintain low relative supersaturation for the growth of large crystals. In homogeneous precipitation, the precipitant is slowly generated by a chemical reaction in the solution to avoid local reagent excesses. For example, urea decomposes gradually to...

Colloidal precipitates

457
The high insolubility of some precipitates can result in an unfavorable relative supersaturation. This can lead to colloidal particles with a large surface-to-mass ratio, where adsorption is promoted. For instance, in the precipitation of silver chloride, silver ions are adsorbed on the surface of the colloidal particles, forming a primary layer. This layer attracts ions of opposite charge (such as nitrate ions), forming a diffuse secondary layer of adsorbed ions. This electric double layer...

Area of Science:

  • Water treatment technologies
  • Materials science
  • Physical chemistry

Background:

  • Freeze desalination (FD) is a promising method for treating industrial saline wastewater in cold climates.
  • A major challenge in FD is the uncontrollable entrapment of salt within the ice structure, hindering efficient ice-salt separation.

Purpose of the Study:

  • To develop a controllable freeze desalination method using electro-assisted crystallization (EAC).
  • To investigate the mechanism of improved ice-salt separation inspired by electrical phenomena in power transmission systems.

Main Methods:

  • Utilizing electro-assisted crystallization (EAC) at -20 °C to induce ice formation.
  • Modulating current density to control ice pore network structure and salt expulsion.
  • Analyzing the ice pore network's open-area percentage and desalination efficiency.

Main Results:

  • EAC created an open ice pore network, increasing the open-area percentage from 25% to 41% with rising current density (10-30 mA cm⁻²).
  • A desalination efficiency of 89.3% was achieved for 35 g L⁻¹ saltwater at 30 mA cm⁻², four times higher than direct FD.
  • The process is attributed to electro-heat synergy, involving Joule heating and dipole polarization effects.

Conclusions:

  • EAC offers a novel pathway for controllable ice-salt separation, inspired by flashover phenomena.
  • This technology presents a potential solution for desalination of water and wastewater in cold regions.
