Removing copper from treated wood waste would allow the to be reused instead of being disposed in landfills. For that reason, a sulfuric acid leaching process for removing with alkaline quaternary (ACQ) and azole (CA) was tested at pilot scale. This process, consisting three 160 min steps room temperature using 0.13 N H2SO4 solution followed by water rinsing steps, allows removal 95% initial pr...

The production of medical isotopes in Chalk River Laboratories facilities (Chalk River, ON, Canada) has resulted a large quantity cemented radioactive waste (CRW) containing valuable elements such as uranium. From the perspective recovering and ultimately recycling from CRW, solubilization key constituents uranium, mercury, cesium been previously investigated using H2SO4/KI. However, to achieve...

Background: A new type of treatment is still needed for sporadic Alzheimer disease. The ion chelating agent (such as M30 and HLA-20) and other kinds of ion chelating agent possess brain tissue permeability. At present, the study has confirmed that ion chelating agent possesses a certain neuroprotective effect on neural degenerative disease. The objective of this study is to explore the related ...

The article considers a sorption method for extracting copper ions from model nitric acid solution based on of electrolytic refining silver with using sorbents bis-picolylamine functional groups: Dowex M-4195 and AXIONIT BPA. possibility to residual concentrations in the less than 10 mg/l is shown. working capacity both samples under batch conditions, as well dynamic exchange full ?onditions (c...

The discovery of a green extraction solvent for natural plants could promote related research. In this study, deep eutectic solvents (DES) were used as coupled with an ultrasound-assisted method (UAE) to extract flavonoids from lotus leaves. Thirty-four different DES performed and choline chloride/urea 40% water was chosen the most promising one, parameters in procedures optimized, resulting hi...
