Area of Science:

  • Materials Science
  • Environmental Science
  • Biotechnology

Background:

  • Keratin-based hydrogels show potential for wastewater remediation.
  • Low surface area and poor mechanical properties limit practical applications of existing hydrogels.

Purpose of the Study:

  • To develop a stable, high-performance bio-hydrogel adsorbent for efficient wastewater purification.
  • To enhance the surface area, porosity, and mechanical strength of keratin-based hydrogels.

Main Methods:

  • Fabrication of a bowl-shaped polydopamine-loaded sponge bio-hydrogel (BPSH) with a hierarchical porous structure.
  • Characterization of the BPSH's structural, mechanical, and adsorption properties.
  • Evaluation of selective adsorption of anionic dyes, particularly Congo red.

Main Results:

  • The BPSH exhibited a hierarchical porous structure with enhanced surface area, porosity, and mechanical strength.
  • Remarkable adsorption capacity for Congo red (Q m up to 2591.9 mg/g at 50 °C).
  • Excellent reusability over three adsorption-desorption cycles, maintaining high adsorption capacities (Q e > 1784 mg/g).

Conclusions:

  • The BPSH is a promising, green adsorbent for effective wastewater purification.
  • The developed material addresses limitations of traditional keratin-based hydrogels.
  • The study highlights a viable strategy for creating advanced adsorbents for environmental applications.
