Battery Recycling Technologies: Recycling Waste Lithium Ion Batteries with the Impact on the Environment In-View

The environmental pollution caused by the valuable chemical components such as cobalt, copper, lithium, mixture of organic electrolyte and salts of either low quality or spent lithium-ion batteries (LiBs) deposited into the environments necessitates responsive recovery technologies. Since Sony made the first commercial lithium-ion cell in 1991, it has been accorded more attention being superior …

Macrozoobenthos Soft Soils of the Far Eastern Marine Biosphere Reserve

This study analyzed the composition and distribution of the macrozoobenthos of the soft soils of the Far Eastern Marine Biosphere Reserve. Found 176 species, classified in six groups: Polychaeta, Bivalvia, Gastropoda, Cumacea, Isopoda, Echinodermata. The greatest variety of typical for polychaete worms (67 species) and bivalves (48 species). Found that the coefficient of variation in …

Impact of Anthropogenic Activities on Genetic Variability of Yeasts inhabiting Mangrove sediments of Dar es Salaam, Tanzania

The objective of the study was to investigate changes in natural yeast populations in mangrove sediments as a result of human (anthropogenic activities) disturbance. DNA techniques in form of Random amplified polymorphic DNA (RAPD) – PCR was employed in this study to assess the genetic variability of yeasts isolated from a natural sediment (non impacted) …

Isotherm, Kinetic and Thermodynamic of Adsorption of Heavy Metal Ions onto Local Activated Carbon

In this work, the adsorption isotherm, Kinetic and thermodynamic of removal of Fe3+, Cu2+, Pb2+ and Zn2+) ions by activated carbon produced from rice husk were studied. The results shown that the Freundlich isotherm model achieved best fit with the equilibrium adsorption data for adsorption of (Fe3+, Cu2+ and Pb2+) ions, it is indicates to …
