  • 5 ways to bridge the gap between best community engagement practice and actual project experiences

    Community engagement and impact assessment go hand-in-hand. Our core principles prize informed consultation and human rights. Many IAIA members also subscribe to the International Association for Public Participation (IAP2), striving to deliver the golden experience promised at the far side of the engagement spectrum. But any of us who’ve spent time in the field know that the ideal ...

  • Properties of vanadium-loaded iron sorbent after alkali regeneration

    The aim of this research was to investigate the regeneration and reuse of a commercial granular iron sorbent (mainly goethite) when used in vanadium removal. A regeneration rate of 3 M NaOH was the highest (85%) achieved, followed by 2 M NaOH (79%) and 1 M NaOH (68%). The breakthrough curves show that the regenerated material can be reused. The BET (Brunauer–Emmett–Teller) surface area ...
