A study on some elements and their phases in sediments of Changjiang Estuary by X-ray spectrometer and X-ray diffractometer

摘要

The studies on the quantitative distribution of the conventional elements and their phases in the sediments of the Changjiang Estuary are of great importance to the understanding of the chemical processes of ion exchange, absorption, desorption and flocculation in the estuary. In this article, ten conventional elements such as Na, Mg, Al, Si, P, K, Ca, Ti, Mn and Fe in the sediments at three stations as Ⅰ_2, Ⅱ_2 and Ⅲ_2 in the Changjiang Estuary were quantitatively analyzed by using X-ray spectrometer with fusion technique. At the same time, the phases of the same specimen in the sediments from the three stations in the Changjiang Estuary were analyzed by X-ray powder diffraction without spiking standard materials.
