Precipitation and Co-precipitation

2.9K
Precipitation and coprecipitation methods can be used to separate a mixture of ions in a solution. In qualitative inorganic analysis, ions that form sparingly soluble precipitates with the same reagent are separated based on the differences in solubility products. For example, consider the separation of Cu(II) and Fe(II) ions by precipitation as insoluble sulfides. First, copper(II) sulfide is precipitated by the addition of acidic H2S, where the dissociation of H2S is suppressed. Adding H2S...

Anodic Stripping Voltammetry (ASV), Cathodic Stripping Voltammetry (CSV), and Adsorptive Stripping Voltammetry (AdSV) are electrochemical techniques used to determine trace amounts of analytes in solution. These methods involve applying a potential to an electrode and measuring the resulting current.
Anodic Stripping Voltammetry (ASV)
ASV is used to determine metals and metalloids at trace levels. It involves two steps: deposition and stripping. First, a negative potential is applied to the...

Extraction: Advanced Methods

624
Metal ions can be separated from one another by complexation with organic ligands–the chelating agent– to form uncharged chelates. Here, the chelating agent must contain hydrophobic groups and behave as a weak acid, losing a proton to bind with the metal. Since most organic ligands used in this process are insoluble or undergo oxidation in the aqueous phase, the chelating agent is initially added to the organic phase and extracted into the aqueous phase. The metal-ligand complex is...

Area of Science:

  • Environmental Science
  • Water Treatment Technologies
  • Mining Engineering

Background:

  • Mining operations can release vanadium into water bodies.
  • Effective treatment of vanadium-contaminated mine water is crucial for environmental protection.
  • Granular ferric oxyhydroxide (CFH-12) is a potential adsorbent for heavy metals.

Purpose of the Study:

  • To investigate the pilot-scale removal of vanadium from mining water using granular ferric oxyhydroxide (CFH-12).
  • To assess the efficiency of CFH-12 in treating mine water with varying vanadium concentrations.
  • To compare CFH-12 performance with lab-scale ferric sulphate coagulation.

Main Methods:

  • Pilot-scale filtration systems (Pilot A and Pilot B) using CFH-12 were operated on different mine water streams.
  • Water quality analyses were performed to monitor vanadium removal efficiency.
  • X-ray fluorescence and X-ray photoelectron spectroscopy were used to analyze the used CFH-12.
  • Lab-scale coagulation experiments with ferric sulphate were conducted for comparison.

Main Results:

  • Vanadium was efficiently captured in both pilot filters, treating influent with high/variable (6.46-99.1 mg/L) and low (0.443-2.33 mg/L) vanadium concentrations.
  • X-ray analysis indicated that CFH-12 was not fully saturated with vanadium and adsorbed organic compounds.
  • Lab-scale coagulation achieved >93% vanadium removal with 350 mg/L ferric sulphate at pH 7.8-7.9, with reduced dosage at pH 4.6-4.8.

Conclusions:

  • Granular ferric oxyhydroxide (CFH-12) is an effective adsorbent for vanadium removal from mining wastewater.
  • CFH-12 demonstrates efficiency across a range of vanadium concentrations and shows potential for long-term use.
  • Ferric sulphate coagulation is also effective, particularly at lower pH, offering an alternative treatment method.
