Pine sawdust biochars produced at 300 and 550 °C with and without steam activation were assessed for its sorption capacity for phosphate and copper (Cu (II)) in aqueous solutions using batch sorption experiments, including isotherm and kinetic studies. This study implied that pine sawdust...
Water contamination by ammonium ions presents huge risks to the ecosystems. This work evaluated the potential application of digested sludge pyrolyzed biochar on ammonium removal. Anaerobic digester sludge was collected from a municipal wastewater treatment plant in Alberta, Canada and pyrolyzed...
Removal of Organic and Inorganic Contaminants from Oil Sands Tailings using Carbon Based Adsorbents and Native SedimentDownload
The extraction and refinement of oil sands bitumen produces substantial quantities of liquid tailings and solid coke. Tailings contain metals and naphthenic acids, which require remediation before mine closure. Adsorption is a potential remediation technique which may reuse stockpiled petroleum...
