Corrosion Scale Characteristics And Lead Oxide Dissolution In Chloraminated Water, Daoping Guo
Corrosion Scale Characteristics And Lead Oxide Dissolution In Chloraminated Water, Daoping Guo
Electronic Thesis and Dissertation Repository
The presence of lead in drinking water is a common issue for utilities where lead pipes are used as service lines in drinking water distribution systems. Dissolved lead concentrations have been linked to the destabilization of stratified lead corrosion scales formed at the inner walls of lead pipe used as drinking water service lines. To develop a framework for lead dissolution control, it is necessary to fully describe the characteristics of the surface layer of the lead corrosion scale in direct contact with drinking water. In the first part of this thesis, a thorough lead corrosion scale characterization is carried …

Influence Of Water Chemistry Parameters On The Dissolution Rate Of The Lead (Ii) Carbonate Hydrocerussite, Caitlin Se Kushnir
Electronic Thesis and Dissertation Repository
This work has focused on the kinetic dissolution of the lead (II) carbonate hydrocerussite (Pb3(CO3)2(OH)2) under four pH conditions (7.5, 8, 9, 10), three dissolved inorganic concentrations (DIC; 10, 20, 50 mg C/L), and three initial hydrocerussite concentrations (10, 20, 50 mg/L) in batch experiments. Experiments were performed in at least duplicate to determine total dissolved lead dissolution curves at short time scales (hr.). All equilibrium dissolved lead concentrations were achieved in 40 minutes or less, and matched trends from previous studies; pH 7.5 and pH 10 corresponding to the highest and …
