Abstract

Total organic carbon content (TOC), Total organic nitrogen content (TN) and their ration (C/N) of lacustrine sediments have been widely used in the Quaternary palaeoenvironment researches. Before measuring the TOC and TN of the sediments, the first important step is to effectively remove the inorganic carbonate, and preserve organic carbon well at the same time, which is the guarantee to good experiment results and accurate palaeoenvironment reconstruction. In order to apply a proper experimental procedure to the Heqing core sediments in Yunnan province, different lithological sediment samples from different depths are used to examine the influence of pretreatment methods, including grain size, the concentration of hydrochloric acid (HCl), and the method of washing the residual acid, on the analysis of total organic carbon content. According to the results of TOC, TN, C/N, and the total inorganic carbonate content (TIC), the pretreatment procedure of Heqing core sediments prior to TOC analysis is established as the followings:under normal condition, a sediment sample is grinded to be uniform and fine (no sieving process), which reacts with enough HCl whose concentration is 2mol/L for 24 hours; then centrifugal acceleration method is employed to cleaning the treated sample by acid to be neutral. This procedure can effectively remove the inorganic carbonate from the sediments, and the results of TOC and TN show good stability and reproducibility. The obtained sequences of TOC, TN, and C/N show good correlation, which all imply the intensity changes of the southwest monsoon.
