Alkali-activated magnetic red mud for Sr2+ adsorption and microwave vitrification into stable iron phosphate glass

Key Points

• Strontium adsorption rates reached 94.5% within 60 minutes, showcasing high efficiency.
• The alkali-activated magnetic red mud effectively captures Sr2+ ions, allowing for environmental remediation.
• Assessment using microwave vitrification leads to the formation of stable iron phosphate glass from the remediated material.
• These findings highlight a potential recycling strategy for hazardous waste materials, promoting sustainability.
