Research & Development
PCA RP348 RESEARCH & DEVELOPMENT Stabilization of Heavy Metals in Portland Cement, Silica Fume/Portland Cement and Masonry Cement Matrices by Javed I. Bhatty, F. MacGregor Miller, Presbury B. West, and Börje W. Öst RP348 99 ABSTRACT The effects of heavy metals on the physical and chemical properties of portland-cement based pastes were studied using different types of cement, four metal oxides, and four soluble metal salts. Type I (high cal- cium aluminate content) and Type V (low calcium aluminate content) portland cements were used to study the effects of their chemical differences on paste properties and metal stabilization. Fresh pastes were tested for workability, initial setting times, and heats of hydration. Hardened pastes were tested for strength and leachability by both TCLP (Toxic Characteristic Leaching Procedure) and column leaching with acetic acid. The cement matrix was an excellent stabilization matrix, better than could be projected from pH consid- erations alone. The investigation also involved examining Type I portland cement paste treated with three metals to- gether—chromium, cadmium and lead, added at very high (1% by mass of cement) and intermediate (1000 ppm by mass of cement) levels. The leaching solutions were acetic acid, “synthetic acid rain” (pH 3 sulfu- ric/nitric acid), and deionized water. A Type N masonry cement matrix was also investigated. The leachabilities were very low throughout the pH range of 6-11 for lead and chromium. At very high pH values, the leachabilities of lead and chromium were significantly higher. Cadmium leachability was neg- ligible above pH 10, but became rapid and highly significant below pH 9. -

Synthesis of Lead Dioxide Nanoparticles by the Pulsed Current Electrochemical Method
Int. J. Electrochem. Sci., 4 (2009) 1511 - 1527 International Journal of ELECTROCHEMICAL SCIENCE www.electrochemsci.org Synthesis of Lead Dioxide Nanoparticles by the Pulsed Current Electrochemical Method Hassan Karami *, Mahboobeh Alipour Nano Research Laboratory, Department of Chemistry, Payame Noor Unirvesity (PNU), Abhar, Iran *E-mail: [email protected] Received: 22 June 2009 / Accepted: 11 November 2009 / Published: 1 December 2009 In this paper, lead dioxide nanoparticles were directly synthesized by pulsed current electrochemical method on the lead substrate in 4.8 M sulfuric acid solution. In order to obatin uniform morphology , narrowest size distribution and best composition of lead dioxide nanoparticles, the effect of experimental variables such as concentration of sulfuric acid, bath temperature, pulse frequency and pulse height (current amount), have been investigated. For conversion of all synthesized species to lead dioxide, each prepared sample was oxidized by low voltage method. The composition, morphology and structure were investigated using Energy Dispersive X-ray Analysis (EDX), scanning electron microscopy (SEM) and X-ray diffraction techniques (XRD). XRD results revealed lead dioxide samples, prepared under optimized experimental conditions, contain only PbO 2 in the range of 24-32 nm. Electrochemical behavior of the prepared electrodes was studied by cyclic voltammetry. The obtained results indicate that pulsed current electrochemical method can be used as a confident and controllable method for direct preparation of the lead dioxide nanoparticles on lead substrate. The lead dioxide synthesized in the optimum conditions showed an excellent discharge capacity (230 mA.h/g) when it was used as the cathode of lead-acid batteries.
