Polyampholytes are charged macromolecules, which carry both acidic and basic groups. These groups dissociate, leaving ions on chains and counter ions in solution, under appropriate conditions, ...

This study investigates the performance of microbial fuel cells (MFCs) fed with municipal sewage water considering parameters such as temperature and cathode materials. Single chamber ceramic MFCs with the cathode exposed ...

Wastewater treatment challenges faced by conventional methods have necessitated the need for alternative/complementary methods that are environmentally benign and efficient especially toward recalcitrant organic pollutants. ...

Chalcopyrite accounts for 70% of all copper bearing minerals and therefore has been studied closely to understand the dissolution kinetics in hope of overcoming the passivation film and increasing the extraction rates ...

An attempt to determine the various phenomena at play and leaching mechanism of chalcopyrite dissolution, was conducted on a chalcopyrite concentrate. The study was performed at atmospheric conditions (room temperature) ...

Coal processing in the refinery industry often lead to the formation of coal tar containing polycyclic aromatic hydrocarbons which are likely to affect human and animal health when released in surface and ground waters. ...
