1电厂煤燃烧后元素硒的分布及对环境的贡献显示文摘对电厂煤、除尘器飞灰、渣及不同粒径的烟道飞灰中痕量元素硒进行研究 .化学分析表明 ,硒在渣和除尘器飞灰中亏损而在细飞灰中富集 ,尤其在 >19 0 μm的飞灰中明显富集 ,富集系数达到 5 . 15 ,造成这种现象的原因一是挥发性元素的挥发 凝结作用 ,二是燃烧产物在燃烧气流中停留的时间 ,三与飞灰颗粒形态有关 ,>19 0 μm的飞灰中多孔颗粒可能是造成其富集的原因 .逐级化学提取实验表明 ,煤中硒主要具有机相关性 (6 9 7% ) ,这也是硒挥发性高的一个主要原因 ;物质平衡计算显示煤中 16 . 5 %的硒随气流直接排放入大气 ,细飞灰中的硒只占 1 1% ,且大部分在 >19 0 μm的飞灰中 ,影响范围小 ,渣中硒对周围环境的影响更小 ,飞灰中的硒具有一定的迁移性 ,也许可以用来改善缺硒土壤 .徐文东 曾荣树 叶大年 X.

2Synthesis of zeolites using fly ash and their application in removing heavy metals from waters显示文摘Three types of zeolite (NaP1 zeolite, analcime and chabazite) were hydrothermally synthesized by reacting fly ash with NaOH solution. The maximum conversion rate from fly ash to single zeolite is about 40%—75%, and the total conversion rate 60%—80%. The synthesis experimental results indicate that factors including vortex, viscosity, temperature, reaction time, and NaOH concentration in the reaction system strongly affect the type and conversion rate of zeolites. The batch experiments of removing Cu2+, Pb2+ and Cd2+ from wastewaters show that the adsorption capacity of zeolites synthesized is higher than that of fly ash.王焰新 郭永龙 杨志华 蔡鹤生 Xavier Querol 2003Science China Earth Sciences2003,46,9:2

5The potential leaching and mobilization of trace elements from FGD-gypsum of a coal-fired power plant under water re-circulation conditions显示文摘Experimental and geochemical modelling studies were carried out to identify mineral and solid phases containing major, minor, and trace elements and the mechanism of the retention of these elements in Flue Gas Desulphurisation(FGD)-gypsum samples from a coal-fired power plant under filtered water recirculation to the scrubber and forced oxidation conditions. The role of the p H and related environmental factors on the mobility of Li, Ni, Zn, As, Se, Mo, and U from FGD-gypsums for a comprehensive assessment of element leaching behaviour were also carried out. Results show that the extraction rate of the studied elements generally increases with decreasing the p H value of the FGD-gypsum leachates. The increase of the mobility of elements such as U, Se, and As in the FGD-gypsum entails the modification of their aqueous speciation in the leachates; UO2SO4, H2 Se, and HAs O2 are the aqueous complexes with the highest activities under acidic conditions.The speciation of Zn, Li, and Ni is not affected in spite of p H changes; these elements occur as free cations and associated to SO42 in the FGD-gypsum leachates. The mobility of Cu and Mo decreases by decreasing the p H of the FGD-gypsum leachates, which might be associated to the precipitation of Cu Se2 and Mo Se2, respectively. Time-of-Flight mass spectrometry of the solid phase combined with geochemical modelling of the aqueous phase has proved useful in understanding the mobility and geochemical behaviour of elements and their partitioning into FGD-gypsum samples.Patricia Córdoba Iria Castro Mercedes Maroto-Valer Xavier Querol 2015Journal of Environmental Sciences2015,27,6:2
