The iron oxide, which contains radioisotopes, can then be disposed of by cementation or encapsulation. Alternately, these chlorides can be washed off of the solids and can then either be recycled or disposed of in some other way.«less. 46 CFR - Ferric chloride solution.

Plessas (7) followed up on this noted effect and investigated arsenic removal by cementation using iron. She investigated the removal of arsenic from synthetic wastewaters (at various pH levels) by flowing solutions over iron scrap (in a column setup). Arsenic concentrations in the range 1 to 5 mg/L were achieved at pH levels of 5 to 6.
A method for the recovery of chemical values, such as metals including zinc, zinc oxide, iron-carbon feedstocks, lead and cadmium, from industrial waste streams which entails treating the waste streams with carbon and an ammonium chloride solution, separating any undissolved components from the solution, displacing metal ions including lead and cadmium from the Cited by: 4.

The reaction of cobalt reduction with borohydride is very complicated. Various authors obtained different reaction stoichiometries and have proposed a number of mechanisms. There are conflicting claims about the removal of cobalt from zinc electrolyte with sodium borohydride.
The present research has focused on the stoichiometry of cobalt reduction with borohydride and on Cited by: A TEXTBOOK OF CHEMISTRY 6 tion or to change its rate of motion. Energy is usually defined, on the basis of etymology, as anything which can do work.
A more satisfactory definition is that energy is anything which may matter in motion or change its rate of motion. The most important forms of energy are mechanical energy, sound, heat, set. Application of the ion-exchange method to remove metallic ions from waters and sewages Z. Hubicki a, A.

A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. A fundamental study of the reductive leaching (decomposition) of chalcopyrite was performed in both sulfate and chloride media.
This was done to understand the physical chemistry of the leaching reactions and the possibility of developing a process flowsheet. The main objective of reductive leaching is to achieve the enrichment of chalcopyrite by rejection of iron and sulfur.
Solutions Solutions were mentioned in Section as homogeneous mixtures. Here solutions are regarded as liquids in which quantities of gases, solids, or other liquids are dispersed as individual ions or molecules. Rainwater, for example, is a solution containing molecules of N2, O 2 and CO2 from air dispersed among the water molecules.
