Molybdate Clustering in Crystallization Solutions

本研究的目的是表征过饱和钼酸盐溶液中团簇形成的性质，主要是那些用于制备钼酸盐催化剂的溶液。该研究涉及浓度、pH值和杂质对钼酸盐团簇形成的程度和它们达到的尺寸的影响。拉曼光谱和光散射技术将得到改进和发展，以获得聚类信息。此外，对在力场作用下的过饱和溶液中形成的浓度梯度的分析也将用于表征团簇的形成。本研究的结果将有助于更好地理解溶液中晶体的成核和生长，以及溶液条件对由这种溶液制备的钼酸盐催化剂的有效性的影响。

The objective of this research is to characterize the nature of cluster formation in supersaturated molybdate solutions, principally those solutions used to prepare molybdate catalysts. The study is concerned with the effects of concentration, pH and impurities on the degree to which molybdate clusters form and on the size which they achieve. Raman spectroscopy and light scattering techniques will be refined and developed to obtain clustering information. In addition, the analyses of concentration gradients which develop in supersaturated solutions subjected to a force field will also be used to characterize cluster formation. The results of this research will contribute to a better understanding of crystal nucleation and growth from solution as well as contribute to the understanding of the effect of solution conditions on the effectiveness of molybdate catalysts produced from such solutions.
