Stability of Mg-sulphate minerals in the presence of smectites: Possible mineralogical controls on H2O and nutrient cycling on Mars
Stability Mg-sulphate minerals presence of smectites mineralogical controls H2O nutrient cycling Mars
2012/3/30
Hydrated sulphate minerals, including kieserite (MgSO4·H2O), gypsum (CaSO4·2H2O), and bassanite (CaSO4·~0.5H2O), have been detected on Mars (Gendrin et al., 2005; Wray et al., 2010), and polyhydrated ...
凹凸棒石是一种性能优良的吸附剂,对小分子极性气体具有很好的吸附性如SO2,H2S和NH3等。适当的热处理可以提高其脱除SO2的能力。文章采用热处理改性的凹凸棒石作为脱硫剂脱除烟气中的SO2,同时考察不同吸附温度下O2浓度和H2O含量对凹凸棒石烟气脱硫的影响。结果表明：在所考察的温度范围（50~200℃）内O2的存在没有影响凹凸棒石吸附SO2的吸附容量;当吸附温度低于100℃时,H2O与SO2存在竞...

2009/5/18
以适量Na2WO4·2H2O, HCl, NaCl和H2O为原料, 从过饱和的角度对4.0% NaCl水溶液中WO3溶解度的超临界现象进行实验探讨. 压力恒定在34 MPa, 接近临界压力31.4 MPa, 温度变化于250~550℃之间, 在快速淬火高压釜中进行实验. 结果表明在临界区域内, WO3溶解度具有超临界现象, 溶解度对温度、密度的变化反应敏感. 本实验温、压条件与许多钨矿床成矿流体的...
利用原位低温拉曼光谱分析技术，对在设定的实验条件下合成的ＣａＣｌ２Ｈ２Ｏ体系和ＭｇＣｌ２Ｈ２Ｏ体系的流体包裹体进行分析研究，结果表明低温下ＣａＣｌ２水溶液和ＭｇＣｌ２水溶液形成的盐水合物具有各自不同的特征拉曼光谱，通过测定特征光谱，能够简易直接的鉴定这些物质，进而确定盐水体系包裹体的成分。因此，原位低温拉曼光谱技术，能够有效地测定Ｃａ２＋和Ｍｇ２＋这两种盐水体系包裹体流体中常见，但显微测温过程...
