The Influence of Water Chemistry on Dissolution Rates of Lead (II) Carbonate Solids Found in Water Distribution Systems 水化学对配水系统中碳酸铅固体溶解速率的影响
发布日期: 2008-11-01
例如,实施铅补救策略 磷酸盐,以控制其分配系统中的铅浓度。这项研究 在流动反应器中使用拉曼光谱实时监测氢化钾转化为低溶解度磷酸铅。然后,这些数据将用于 为管理产品转化的具体过程开发概念模型 氢氰酸盐转化为磷酸铅。重要的过程包括:溶解、成核 以及晶体生长、粒子-粒子相互作用或直接固态转化。在 在不久的将来,每种方法的数学模型都将进行测试,以提供见解 进入转化过程。包括20个参考文献、图表。
Utilities are implementing lead remediation strategies, such as the addition of phosphate, to control lead concentrations in their distribution systems. This research monitors the transformation of hydrocerussite to lower solubility lead phosphates in real-time, using Raman spectroscopy in a flow through reactor. The data will then be used to develop conceptual models for the specific processes governing the transformation of hydrocerussite to lead phosphates. Important processes include: dissolution, nucleation and crystal growth, particle-particle interactions, or direct solid-state conversion. In the near future, mathematical models for each approach are being tested to provide insight into the transformation process. Includes 20 references, figures.
