IR-SPECTROSCOPY AND X-RAY PHASE ANALYSIS OF THE CHEMICAL COMPOSITION OF GALLSTONES
Abstract
The composition of inorganic and organic parts of gallstones is investigated by the methods of X-ray phase analysis and IR spectroscopy. It is shown that cholesterol, bilirubin, calcium bilirubinate, calcium carbonate, and calcium hydrogen phosphate are the parts of gallstones. Meanwhile, cholesterol is prevailing. A layered separation of the gallstone as well as a separation of its inorganic part by the annealing are carried out. It is established that the inorganic compounds predominate in the outer layer of the gallstone, which is related to the mechanism of its formation. The composition of the inorganic part includes calcium carbonate of two modifications: calcite and waterite.
