Extraction: Advanced Methods

446
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
  • Adsorption Processes

Background:

  • Groundwater contamination by arsenate poses a global public health and environmental risk.
  • Sustainable water treatment necessitates high removal efficiency at minimal cost, particularly for adsorption-based methods.
  • Chitosan-coated bentonite (CCB) is explored as a potential adsorbent for arsenate removal.

Purpose of the Study:

  • To investigate the adsorption of arsenate from groundwater using CCB in a fixed-bed column.
  • To apply fuzzy multi-objective optimization to determine optimal process conditions (flow rate, initial concentration, CCB dosage).
  • To analyze the trade-offs between adsorption capacity, energy consumption, and operational costs.

Main Methods:

  • Fixed-bed column adsorption experiments.
  • Fuzzy multi-objective optimization using LINGO 20 software.
  • Box-Behnken design for empirical modeling and Pareto frontier analysis using the ε-constraint method.

Main Results:

  • Empirical models were developed to predict adsorption capacity, energy consumption, and cost based on process variables.
  • The Pareto frontier illustrated the trade-off between adsorption capacity at breakthrough (12.34–12.96 μg/g) and total operating cost (955.83–1106.32 USD/kg).
  • A compromise solution yielded an adsorption capacity of 12.90 μg/g and a total operating cost of 1052.96 USD/kg with 35.46% overall satisfaction.

Conclusions:

  • Fuzzy optimization effectively identified optimal conditions for arsenate adsorption using CCB.
  • The study provides a strategic decision-making framework for stakeholders implementing fixed-bed adsorption systems.
  • This approach balances performance and economic viability for sustainable groundwater remediation.
