With the development trend and technological progress of lithium batteries, battery market is booming, which means that consumption demand for batteries has increased significantly, and, therefore, a large number discarded will be generated accordingly. Solvent extraction promising approach because it simple. low in time easy to industrialize. This paper focused on selective recovery cobalt (Co...

A novel, rapid, simple and sensitive dispersive liquid-liquid microextraction method based on the solidification of floating organic drop (DLLME-SFO) combined with high performance liquid chromatography-ultra violet detection (HPLC-UV) was used to determine acrylamide in potato chips. The derivation of the acrylamide happened in the presence of KBr, KBrO3, H2SO4. Based on studies, 1-undecanol w...

In this study, solvent extraction is applied for extracting nickel from sulfate solutions containing iron and cobalt ions. This process can also be the cleaning of waste increasing solution concentrations after leaching low-grade ores. Di-2-Ethylhexyl phosphoric acid (D2EHPA) was used as an extractant purpose. Effects pH, aqueous/organic (A/O) phase ratio, iron, ion contents on efficiency were ...

This preliminary study aims to obtain the lithium compounds from a geothermal brine through solvent extraction. The samples were collected PT Geodipa Energi Geothermal Power Plant in Dieng, Central Java, Indonesia. ICP analysis was conducted measure chemical composition. Brine’s content 62.73 ppm with dominant impurities silica (Si), calcium (Ca), potassium (K), sodium (Na), and boron (B). Sili...

inulin is widely used in functional foods throughout the world for its health-promoting and technological properties. helianthus tuberosus is cultivated widely in the northern part of iran. helianthus tuberosus can be a valuable source of inulin. to optimize conventional extraction of inulin, various combinations of time, temperature, and solvent: solid ratio, were used. in this research, a ser...
