Adsorption Mechanism of Lead on Wood/Nano-Manganese Oxide Composite

Discharge of untreated industrial wastewater containing heavy metals such as Pb2+ is hazardous to the environment due to their high toxicity. This study reports on the adsorption, desorption, and kinetic study on Pb2+ removal from aqueous solutions using wood/Nano-manganese oxide composite (WB-NMO). The optimum pH, contact time and temperature for adsorption were found...

Lead and Lead Compounds

A Comparative Investigation of Lead Sulfate and Lead Oxide Sulfate Study of Morphology and Thermal Decomposition

The compound lead oxide sulfate PbSO4.PbO was prepared in our laboratory. The Thermal behavior of PbSO4 was studied using techniques of Thermogravimetry under air atmosphere from 25 to 1200 ̊C. The identity of both compounds was confirmed by XRD technique. Results obtained using both techniques support same decomposition stages for this compound. The electron microscopic investigations are made ...

Evaluation of total and differential white blood cell counts in workers exposed to lead

Introduction: Lead is a toxic heavy metal that has adverse health effects on blood parameters. About 80% of lead produced is used in batteries, especially vehicle batteries. Therefore, the present study aimed to assess the hematological changes, including total and differential white blood cell (WBC) counts in battery workers exposed to lead, and compare with the non-exposed group. Materials a...

Preparation and characterization of Epoxy/Lead oxide nano-composite for shield against gamma and X-rays

Polymer nano-composites are a group of materials that represent proper mechanical, chemical, thermal and optical properties due to the presence of certain percentages of a filler in a polymeric matrix. In this study lead oxide nanoparticles were prepared by direct precipitation method. Then the lead oxide-epoxy resin nanocomposite was prepared by mixing (without solvent) with different weight p...
