ORNL system eliminates perchlorate, helps scientists trace source
... Conventional treatments use tiny resin beads to trap the perchlorate, but the spent resin becomes contaminated, and disposal is costly or impractical. The ORNL system removes and breaks down perchlorate into harmless chloride and water and recharges the resin so it can be reused many times. The ...Cars, not crops, should be chief targets in reducing greenhouse gases
