Perchlorate Remediation in Aquatic Systems by Zero Valent Iron
Perchlorate Remediation in Aquatic Systems by Zero Valent Iron

Acid, treatment of ,iron filings, significantly enhanced the reduction rate of perchlorate, and the reduction rate was correlated reasonably well by pseudofirst-order reaction kinetics. A linear correlation relating the reaction rate constant to the square of ,iron, dosage was developed which predicted reasonably well the performance of flow through experiments.
