    Abstract: The synthesis of nano-CaO can be produced from natural resources, chemical compounds, and waste containing calcium such as clamshell (Geloine sp.). The research aims to study the effect of temperature and reaction time (sol formation) on the yield of nano-CaO after the calcination process and to characterize the Ca(OH)2 and nano-CaO obtained.

    Abstract: Abattoir wastewater (AWW) contains a high level of organic pollutants due to the presence of toxic contaminants such as blood, feces from animals, and detergents from cleaning activities. In this study, the wastewater from the slaughterhouse was treated with a cobalt-catalyzed persulfate oxidation reaction to determine how well persulfate works as ... Show More
