    Abstract: In recent years, much attention has been focused on cobalt catalysis because of its abundance on Earth, low toxicity, and low cost. A lot of work has been focused on catalysis with cobalt porphyrin. A very interesting chemical reaction catalysed by cobalt(II) porphyrin is the Oxidation of methanol to formaldehyde. The formaldehyde formed in this re... Show More

    DOI: 10.11648/j.sjc.20221006.13
    Abstract: Water quality monitoring is of fundamental importance for health and environmental protection. Conductivity and the total dissolved substance (TDS) are two important water quality parameters. Their monitoring requires good calibration of the measuring equipment and correct assessment of the measurement uncertainty so that the water quality limits c... Show More

    Abstract: Short-lived climate pollutants (SLCPs) are air pollutants and Greenhouse Gas (GHG) responsible for air pollution and climate change. They have a costly impact on health and the environment. Waste management activities are one of the sources of emissions of these pollutants. This Master's thesis falls within this theme. The categorization of sources... Show More
  • Treatment of Faecal Sludge by Two Biochemical Processes

    DOI: 10.11648/j.sjc.20221006.15
    Abstract: Untreated raw faecal sludge is generally reused as fertilizer by some farmers and market gardeners to improve their production areas. However, untreated sludge contains pathogenic germs which, via the faecal-oral route, can present a microbial risk for consumers of fertilized products. To reduce this risk, the objective of this work was to evaluate... Show More
