Overview

Demonstrates effective antibiotic removal in water using spray-dried zinc-alginate microparticles, suggesting a solution for antibiotic resistance.

Key Points

  • The study aims to evaluate the effectiveness of spray-dried zinc-alginate microparticles in removing antibiotics from water.
  • Produced crosslinked zinc-alginate microparticles via spray drying at varying zinc concentrations.
  • Evaluated particle characteristics using FTIR, SEM, and ICP-MS.
  • Conducted antibiotic removal studies using ciprofloxacin and amoxicillin as model compounds.
  • Applied kinetic modeling to understand the adsorption mechanism.
  • Zn-Alg-SD microparticles showed improved uniformity and water stability.
  • High adsorption capacity for ciprofloxacin with a 20-fold increase compared to conventional methods.
  • Kinetic modeling suggested a chemosorption mechanism supporting zinc-mediated complexation.
