Degradation of aliphatic hydrocarbon – dodecane and hexadecane in the presence of potassium ferrate. ▪, dodecane; ∙, hexadecane. Incubation time with ferrate was 1 hour. An incubation over 24 hours produced similar results. Each data point represents the mean of three replicate experiments. Error bars represent +/- one standard deviation of the three replicates. The Y-axis shows integrated peak areas of analytes directly related to concentration. The X-axis shows the amount (mg) of K2FeO4 added to reaction mixtures containing 4 mg of hydrocarbon.
