摘要：采用^(57)Fe穆斯堡尔谱学方法,研究微波-磁分离法脱硫机理及微波辐照深度对脱硫率的影响。结果表明,微波选择性介质加热,可以激励煤中顺磁性黄铁矿FeS_2热解,使其转化为非化学计量的磁黄铁矿Fe_(1-x)S(0Mossbauer spectroscopy was used to determine the transformations of pyrite inherent in coal before and after microwave heating/ magnetic separation. The influence of irradiation time of microwave on the removal of pyrte in coal was examined. The results for phase analyses show that the selective dielectric heating of microwave can convert the paramagnetic pyrite in coal to moderately ferro magnetic pyrrhotite Fe_(1-x)S (0
