Pine tree materials, modified pine bark (MPB) and pine cone (MPC), effectively remove nickel ions from water. MPB achieved 97% removal efficiency at pH 8, demonstrating a viable eco-friendly method for heavy metal remediation.

Area of Science:

  • Environmental Science
  • Materials Science
  • Chemistry

Background:

  • Nickel ions pose significant environmental and health risks.
  • Effective and sustainable methods for nickel ion removal from aqueous solutions are crucial.
  • Natural adsorbents offer a promising alternative to conventional treatment methods.

Purpose of the Study:

  • To investigate the efficiency of modified pine tree materials for nickel ion removal.
  • To evaluate modified pine bark (MPB) and modified pine cone (MPC) as adsorbents.
  • To determine optimal conditions for nickel ion adsorption using these natural materials.

Main Methods:

  • Pine bark and pine cone were modified using hydrochloric acid (HCl).
  • Adsorption experiments were conducted to determine optimal adsorbent dosage, stirring rate, contact time, and pH.

  • Adsorption isotherms were studied to understand the adsorption mechanism.

    • Main Results:

    • Modified pine bark (MPB) achieved a maximum nickel ion removal efficiency of 97% at pH 8.
    • Modified pine cone (MPC) achieved a maximum nickel ion removal efficiency of 80% at pH 8.
    • Adsorption isotherms provided insights into the interaction between nickel ions and the adsorbents.

    Conclusions:

    • HCl-modified pine tree materials, particularly MPB, are effective adsorbents for nickel ion removal from aqueous solutions.
    • These natural adsorbents present a sustainable and cost-effective approach for heavy metal remediation.
    • Further research can optimize these materials for large-scale industrial applications.
