Biological Leaching and Chemical Precipitation Methods for Recovery of Co and Li from Spent Lithium-Ion Batteries

ACS Sustainable Chemistry and Engineering, 2018
Spent Li-ion batteries (LIBs) are highly rich in cobalt and lithium that need to be recovered to reduce shortages of these valuable metals and decrease their potential environmental risks.

Effects of CEOR Chemicals on Asphaltene Precipitation

SPE Annual Technical Conference and Exhibition, 2018
Abstract Enhanced oil recovery methods are appealing to increase oil recovery from reservoirs due to market pressures in times of lower oil price. Chemical enhanced oil recovery (cEOR) methods such as ASP involve the use of alkali, surfactant, and polymer, to create an ultralow interfacial tension (IFT) between microemulsion and oil ...

Chemical composition of precipitation at background level

Atmospheric Research, 2010
Abstract Chemical composition of precipitation collected from a rural forest station near Bhubaneswar in the east coast of India during 2005–2007 was studied. The rainwater and dust-fall washings were collected through a wet-only collector and a bulk collector placed together and the second bulk collector located 500 m apart in the same locality. NH4+

A Chemical Precipitation Method Preparing Hollow-Core-Shell Heterostructures Based on the Prussian Blue Analogs as Cathode for Sodium-Ion Batteries.

Small, 2018
Prussian blue and its analogs are regarded as the promising cathodes for sodium-ion batteries (SIBs). Recently, various special structures are constructed to improve the electrochemical properties of these materials.

Chemical Composition of the Precipitation Over the Netherlands

1981
Abstract The chemical composition of precipitation may have a great influence on the quality of ground water. In the Netherlands precipitation is collected on several sampling sites which are homogeneously distributed over the country. As an example maps with isolines of the ammonium, chloride, sulphate and nitrate content of precipitation collected ...

Sulfate removal from waste chemicals by precipitation

Journal of Environmental Management, 2009
Chemical oxidation using Fenton's reagent has proven to be a viable alternative to the oxidative destruction of organic pollutants in mixed waste chemicals, but the sulfate concentration in the treated liquor was still above the acceptable limits for effluent discharge.
