Effects of pH on dechlorination of trichloroethylene by zero-valent iron

The surface normalized reaction rate constants ( k sa) of trichloroethylene (TCE) and zero-valent iron (ZVI) were quantified in batch reactors at pH values between 1.7 and 10. The k sa of TCE linearly decreased from 0.044 to 0.009 l/h m 2 between pH 3.8 and 8.0, whereas the k sa at pH 1.7 was more t...
