Overview

Randomized trial evaluates heavy metal immobilization in Vertisol, suggesting optimal pyrolysis temperature enhances biochar efficacy.

Key Points

  • The aim is to evaluate how different pyrolysis temperatures affect the ability of sewage sludge biochar to immobilize heavy metals in contaminated soils.
  • Evaluated biochar produced at 350, 450, and 600 °C for its effectiveness in immobilizing heavy metals.
  • Conducted sequential extraction and principal component analysis to assess performance in tropical Vertisol.
  • Analyzed ecological risk indices and metal distribution among mobile and stable fractions.
  • SSB450 reduced potential ecological risk index from 139.06 to 65.23, a 53.1% decrease.
  • Mobile fraction of lead decreased from 69.5% to 35.2% with SSB450 and SSB600 applications.
  • SSB350 showed limited stabilization of cadmium, indicating lower effectiveness at 350 °C.
