The iron and steel industry is one of the largest contributors to global emissions of carbon dioxide, especially in the sintering process. Biomass has been widely suggested as an alternative, safer and sustainable fuel in order to reduce pollutant emissions from the iron and steel industry. It is beneficial to replace coke with biochar in iron sintering, as this method provides a large amount of greenhouse gases. In this work, coke was substituted as an alternative fuel in the sintering … Continue reading “Phase Change of Low Grade Iron Ore during Sintering and Reduction with Oil Palm Empty Fruit Bunch”

Scientific Research: Biosorption and Chemical Precipitation of Lead Using Biomaterials, Molecular Sieves, and Chlorides, Carbonates, and Sulfates of Na & Ca

Lead, a heavy metal, is a wellknown contaminant in water and has been reported to cause serious health implications to humans, animals, and plants. One of the processes for heavy metal remediation of contaminated water is chemical precipitation. In this present work, chemical precipitation of lead from a contaminated aqueous matrix by chlorides, carbonates, and sulfates of sodium and calcium was compared to lead removal by molecular sieves and biomaterials (fish-bone, grape and spinach). The order of lead removal from … Continue reading “Scientific Research: Biosorption and Chemical Precipitation of Lead Using Biomaterials, Molecular Sieves, and Chlorides, Carbonates, and Sulfates of Na & Ca”
