  mineral surface chemistry
A common tenet in mineral surface chemistry is that structural and chemical defects are focal points for both surface and bulk reaction.
      
In so far as the mechanism of interaction is affected by mineral surface chemistry, so is the nature of the fractionation process.
      
The data indicate that fractionation behavior of NOM is dependent on mineral surface chemistry in addition to sorbent affinity for organic C.
      
The large difference in NOM sorption between goethite and birnessite is attributed to differences in mineral surface chemistry.

本文用分子轨道理论指数和基团电负性研究浮选结构-活性关系三种因素中的价键因素和疏水-亲水因素。用计算数据组成一组药剂活性判据,预测药剂浮选行为(作用专属性,选择性和能力大小)以及解释机理,讨论药剂在矿物表面化学吸附时键合原子位置,价键种类,分子中极性/非极性结构关系及各原子间的相互影响等,为寻找特定性能药剂指出途径。

The kinetics of dissolution of Panzhihua ilmenite in sulfuric acid solutions was investigated at the range 95—118℃. The Arrhenius actiYation energy was found to be 44.7 kJ mol~(-1) The leaching reaction in sulfuric acid solutions at the concentrations 5.3—11.5 mol·dm~(-3) followed the shrinking core model, and the kinetics of reaction was controlled by the chemical process on the mineral surfaces.

With the technique of x-ray photoelectron spectroscopy(XPS) surface chemistry and adsorption mechanism of calcite from the laterite in Guizhou have been studied. XPS of the mineral surface reveals that the surface and the body of the mineral are quite different from each other in chemical composition, incorporation and structure. The heterogenous characteristics of the mineral constitute a major kinetic cause for the chemical reactions in the mineral. It is the specific adsorption and desorption of the mineral...

With the technique of x-ray photoelectron spectroscopy(XPS) surface chemistry and adsorption mechanism of calcite from the laterite in Guizhou have been studied. XPS of the mineral surface reveals that the surface and the body of the mineral are quite different from each other in chemical composition, incorporation and structure. The heterogenous characteristics of the mineral constitute a major kinetic cause for the chemical reactions in the mineral. It is the specific adsorption and desorption of the mineral that lead to mobilization and agglomeration of some elements and that become an important mechanism of the environmental pollution in the laterite.

应用X射线光电子谱(XPS)技术,研究了贵州岩溶地区红土中方解石及氧化铁矿物表面化学特征及吸附机理。方解石及氧化铁矿物表面XPS图及碳元素结合能区域的高分辨XPS分析表明,方解石及氧化铁矿物表面和整体之间在化学成分、状态和结构方面存在明显差异。矿物表面的这种非均匀性特征,是矿物表面化学反应的重要动力学起因。方解石及氧化铁矿物等地表矿物表面对元素的选择性吸附和解吸作用的表面化学反应是造成岩溶环境中许多元素迁移、富集及污染的重要机理。
