One-pot synthesis of semiconducting PbS nanorods within polyphenylene sulphide matrix.

Herein we report an extremely simple one-pot synthesis of lead sulphide nanorods inside the engineering thermoplastic (i.e. polyphenylene sulphide) which plays a dual role of stabilizing matrix as well as a chalcogen source.

Landfill leachate treatment by the combination of physico-chemical and electrochemical methods.

Leachate originating in landfills, where industrial solid wastes are disposed of, is a complex wastewater that could exert high environmental impact. In this paper, treatment of landfill leachate, particularly removal of chemical oxygen demand (COD) through adsorption, chemical oxidation (KMnO4), electrocoagulation and electrochemical oxidation processes was studied. The combined processes, viz.
