lignite A
6.A test for the adsorption of chromium-ion with the nitrify lignite has been carried out. The capacities of lignite, adsorption kinetics, adsorption models and the ef-fect of pH were studied. The results indicated that the nitrify lignite had good adsorption properties to chromium-ion and the adsorption isotherms were consistant with Langmuir equation.
7.Identification of the phase composition of one and the same microspherical particle of uraniferous lignite ash was performed by means of four physical methods, i. e., the liquid nuclear emulsion microradiography, electron-probe analysis of microrange composition, X-ray diffraction analysis with Debye camera, and a scanning electron-microscopy, which conspired towards data determinative for identification.
8.Pittsburgh, June 27, 2007 — Emerson Process Management received a $27 million contract to modernize generating units 3 and 4 of the largest lignite-fired power plant in Europe, the Belchatow Power Plant in Poland.
9.In this paper , identification of the phase composition of micro-sphorical particae of uraniferous lignite ash was performed by means of four methods , i.e. , the liquid nuclear emulsion microradio-graphy , X-ray diffraction analysis with Debye camera , electron-ns probe analysis of microrange composition , and a microscope-viewe. It has been proved that the spherical particle exists in the form of U1-xO2 , and Fe3O4
