Perchlorate Remediation in Aquatic Systems by Zero Valent Iron

Perchlorate remediation by zero valent ,iron, was studied in this paper. ,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 ...
