文摘
- •
ZVI-activated persulfate oxidation could efficiently degrade bentazon in water.
- •
Both ZVI concentration and PS dose had an inflection point in ZVI-PS system.
- •
Low bentazon concentration, low pH and high temperature favored the reaction.
- •
Different coexisting ions exhibited different effects.
- •
Most of bentazon transformed to intermediate products instead of carbon dioxide.
