Title: Synthetic Humic Acid Materials for Improved Water Purification

Radford University students are designing new coatings to help ordinary sand capture heavy metals, such as cadmium and lead, as well as arsenic and organic contaminants. The design is based on humic acid, a naturally occurring compound that chemically grabs water pollutants. To improve performance the team is designing a synthetic humic acid made from sugars with the potential to be more economical and effective than current processes.

Challenge Area(s): Materials & Chemistry, Water
