Abstract

Silicates and aluminosilicates form 95 % of Earth surface rocks and contribute substantially to building materials. Understanding their dissolution is essential for understanding the impact of mineral-H2O-CO2 equilibria and rock weathering on the carbon cycle and for optimising material performance and safety. Predicting dissolution rates is a key but traditional empirical models rely on non-integer reaction orders, which have little meaning, mechanistically and often must be determined for each system separately.

简单硅酸盐和铝硅酸盐矿物及玻璃溶解随pH值和温度变化的一般微动力学模型

硅酸盐和铝硅酸盐占地球表面岩石的95% %，是建筑材料的重要组成部分。了解它们的溶解对于理解矿物- h2o - co2平衡和岩石风化对碳循环的影响以及优化材料性能和安全性至关重要。预测溶解速率是关键，但传统的经验模型依赖于非整数反应顺序，这在机械上没有什么意义，而且往往必须对每个体系单独确定。

期刊介绍： Chemical Geology is an international journal that publishes original research papers on isotopic and elemental geochemistry, geochronology and cosmochemistry. The Journal focuses on chemical processes in igneous, metamorphic, and sedimentary petrology, low- and high-temperature aqueous solutions, biogeochemistry, the environment and cosmochemistry. Papers that are field, experimentally, or computationally based are appropriate if they are of broad international interest. The Journal generally does not publish papers that are primarily of regional or local interest, or which are primarily focused on remediation and applied geochemistry. The Journal also welcomes innovative papers dealing with significant analytical advances that are of wide interest in the community and extend significantly beyond the scope of what would be included in the methods section of a standard research paper.
