Citric Acid Process of Soil Remediation (Virtual Exploration Lab, Grades 9-12)

Citric acid, a naturally occurring organic complexing agent, can be used to remove toxic metals from soil. Students learn about the technique that Brookhaven Lab developed by performing a simple procedure to remove and recover iron, a model for a metal contaminant, by forming a soluble iron-citrate complex. Next, students will use a spectrophotometer to analyze the concentration of iron in the soil.
