ABSTRACT: The reductive dechlorination of carbon tetrachloride (CT) by Fe I I −Fe I I I hydroxide (green rust) intercalated with dodecanoate, FeII4FeIII2(OH)12(C12H23O2)2·yH2O (designated GRC12), at pH ∼ 8 and at room temperature was investigated. CT at concentration levels similar to those found in heavily contaminated groundwater close to polluted industrial sites (14− 988 μM) was reduced mainly to the fully dechlorinated products carbon monoxide (CO, yields >54%) and formic acid (HCOOH, yields >6%). Minor formation of chloroform (CF), the only chlorinated degradation product, was also detected (yields
