| Abstract | Considerable quantities of organic material, insoluble in common organic solvents, are known to be associated with the inorganic minerals present in oil sands. This insoluble organic matter (IOM) consists of both humic and non-humic components. This organic matter is believed to be partly responsible for the intractability of the sludge. In our previous work we have successfully isolated non-extractable residual organic matter from oil sand tailings using oil phase aggromeration and acid dissolution techniques. In this investigation we have isolated humic acids from a number of samples of mineral solids obtained from Syncrude sludge pond tailings. These solids were obtained from sludge using different experimental conditions such as soxhlet extraction followed by air drying of solids and centrifugation followed by air drying or vacuum drying of solids. Humic matter was extracted from these solids using a mixture of Na₄P₂O₇ and NaOH which extracts both humic acids as well as organometallic compounds. Extraction with NaOH yielded humic acids from this composite organic material. The various samples of humic acids isolated were studied using elemental analysis and ¹³C NMR spectroscopy. |
