TL;DR: In this article, the authors used Potassium dichromate supported on neutral alumina as a heterogeneous catalyst for the liquid phase oxidation of hydrocarbons and achieved a rate of conversion of 3.8% h-1 (0.39 turnover s-1) at a reaction temperature of 130 °C for a period of ca. 10 h before catalyst deactivation.

TL;DR: In this paper, four kinds of methods,TOC analyzer, loss-on-ignition (LOI),950-C LOI and hydrated heat potassium dichromate oxidation-colorimetry, were employed to determine the content of organic matter (OM) of the sediments in Changjiang River.
Abstract: Four kinds of methods,TOC analyzer,550℃ loss-on-ignition(LOI),950℃ LOI and hydrated heat potassium dichromate oxidation-colorimetry,were employed to determine the content of organic matter(OM) of the sediments in Changjiang RiverThe accuracy and precision of the above methods as well as their influences on the measurements of content of soil OM were discussedStandard OM reference materials and five sediment samples from Qinhuai River in Nanjing were analyzedThe results of the four methods were comparedA conclusion is drawn that the test accuracy of the four methods has the sequence of TOC analyzer,550°C LOI method,hydrated heat potassium dichromate oxidation-colorimetry and 950°C LOI methodThe precision has the sequence of TOC analyzer,hydrated heat potassium dichromate oxidation-colorimetry,550°C LOI method and 950°C LOI methodThe TOC analyzer method and the 550°C LOI method are superior,and the other two should not be employedThe results of the hydrated heat potassium dichromate oxidation-colorimetry are too small and the 950°C LOI method leads to large errors in the results
