  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.
      


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。

The dissolution characteristics of scheelite, calcite and apatite and their effects on surface property and floatability of the minerals were investigated in the light of solution chemical calculation, AES, atomic absorption and flotation tests. It has been revealed that chemical reaction of dissolved species from one mineral on other mineral surface will result in changes in surface property, electrokinetics and floatability of the minerals. This is an essential reason why it is difficult to achieve flotation...

The dissolution characteristics of scheelite, calcite and apatite and their effects on surface property and floatability of the minerals were investigated in the light of solution chemical calculation, AES, atomic absorption and flotation tests. It has been revealed that chemical reaction of dissolved species from one mineral on other mineral surface will result in changes in surface property, electrokinetics and floatability of the minerals. This is an essential reason why it is difficult to achieve flotation separation of the sparingly soluble minerals.

根据溶液化学计算、原子吸收光谱、俄歇电子能谱及浮选实验,研究了白钨矿、方解石、磷灰石体系中矿物溶解平衡及其对矿物表面性质与可浮性的影响。这些半可溶性盐类矿物溶解度相对较大,一种矿物溶解组分在另一种矿物表面的化学反应,将导致矿物表面化学组成、电性及可浮性的变化,这是半可溶盐类矿物浮选分离困难的本质原因。

On the basis of determination and adsorption experiments of fluorine, surface chemistry of minerals and soil chemistry of samples, geochemical characteristics and migration enrichment mechanism of fluorine in the rock, soil and water system have been studied. The contents of fluorine in rock, soil and water system are characterized by the fluorine enrichment in deep groundwater (under the depth of 100m) and soil, but there are low fluorine contents (less than 0.5 mg/l) in shallow groundwater and surface water....

On the basis of determination and adsorption experiments of fluorine, surface chemistry of minerals and soil chemistry of samples, geochemical characteristics and migration enrichment mechanism of fluorine in the rock, soil and water system have been studied. The contents of fluorine in rock, soil and water system are characterized by the fluorine enrichment in deep groundwater (under the depth of 100m) and soil, but there are low fluorine contents (less than 0.5 mg/l) in shallow groundwater and surface water. Adsorption and desorption of fluorine at the surface of goethite is an important mechanism for fluorine migration and enrichment in the soil water system of the karst areas.

通过对研究区碳酸盐岩—土—水系统中氟的系统测定和吸附实验,结合矿物表面化学和土壤化学研究,揭示了岩溶地区岩—土—水系统中氟的地球化学特征和迁移富集机理。黔中岩溶地区深层地下水(100m以下)和土层具有高氟异常特征,而浅层地下水和地表水含氟较低(大多在0.5mg/l以下)。以含石膏碳酸盐岩为主的三叠纪海相地层是该区土水中氟的主要来源。土层中针铁矿表面对氟的专性吸附及其解吸作用是岩溶地区土水系统中氟迁移和富集的重要机理。
