  abstract = {{P}otassium permanganate ({KM}n{O}4) has been an effective technology for the in situ chemical oxidation ({ISCO}) of many organic compounds including chlorinated alkanes and alkenes, but it has rarely been applied for oxidizing aromatic organochlorines. {T}his study confirms the ability of permanganate to oxidize an aromatic chlorinated compound, pentachlorophenol ({PCP}), in an efficient manner at neutral p{H}. {T}he rate of the reaction between {KM}n{O}4 and {PCP} was calculated and the results indicated that the reaction between {PCP} and permanganate is relatively fast with a second-order rate constant k approximate to 30{M}(-1)s(-1). {B}esides the kinetic aspect, the authors identified the main reaction by-products, and proposed a possible reaction mechanism scheme. {T}he general pathway shows the formation of chlorinated intermediates, and ultimately, the complete mineralization to chloride, water, and {CO}2 confirmed by total organic carbon and chloride measurement in solution. {F}low-through column experiments, consisting of flushing a {PCP}-contaminated sandy or natural soil with oxidant, showed the good ability of permanganate to eliminate the pollutant. {A}fter 24h of treatment, 77% and 56% of {PCP} abatement were obtained for sandy and natural soil, respectively. {T}hese findings show the high potential of permanganate for the in situ remediation of aromatic organochlorine contaminated soils.},
