BACKGROUND The interaction between Ca-HAP and Pb(2+) solution can result in the formation of a hydroxyapatite-hydroxypyromorphite solid solution [(PbxCa1-x)5(PO4)3(OH)], which can greatly affect the transport and distribution of toxic Pb in water, rock and soil. Therefore, it's necessary to know the physicochemical properties of (PbxCa1-x)5(PO4)3(OH),(More)
BACKGROUND The substitution of Ca(2+) in Ca-hydroxylapatite by toxic Cd(2+) can cause the forming of Cd-hydroxylapatite and is a significant issue in a great variety of research areas, which hence needs an understanding of the essential physicochemical characteristics. Unfortunately, the solubility product and thermodynamic data for Cd-hydroxylapatite in(More)
The Infrastructure Technology Institute develops advanced methods for monitoring infrastructure condition and performance to assist owners and operators with critical decisions concerning structural integrity, renewal, and rehabilitation.

The denitrifying phosphorus removal characteristics of three municipal wastewater treatment plants (MWTPs) with different process, i.e., the Carrousel system included an oxicaerobic stage (A/O), the anoxic-aerobic Carrousel system with separated pre-anaerobic tank (A/C) and the typical three-stageanaerobic¨Canoxic¨Caerobic process (A2/O), were(More)
A series of the Pb5(PxAs1-xO4)3Cl solid solutions were directly prepared through aqueous precipitation method. The results of the elemental analysis, XRD, FT-IR and SEM characterization have confirmed the forming of the mimetite/pyromorphite solid solutions. The XRD analysis indicated that the end-member components of the solid solutions were well matched(More)
The low-cost activated carbon was prepared from sugarcane bagasse, an agricultural waste material, by chemical activation with different reagents. Orthogonal experimental design was applied to study the influence of activation temperature, activation time and chemical ratio of reagents to sugarcane bagasse on the chemical activation process of sugarcane(More)
