Magnetic Properties of Metals3d, 4d and 5d Elements, Alloys and CompoundsIn materials science, a knowledge of the phases present in a chemical system at equilibrium is fundamental. Phase diagrams permit one to visualize how the phase equilibria change as temperature, pressure, composition, etc. ...
Platinum group metals (PGMs) assume an important role within the chemistry and chemical engineering due to their exceptional chemical stability in high temperatures and various environmental conditions. Their unique attributes make them highly demanded materials across an array of industries. Nevertheless, ...
This insightful work adjusted the length of ether-oxygen chain groups in covalent organic framework pores to modulate the solvation/coordination capacity of membrane pores and investigated their effect on Li+ and Mg2+ transmembrane selectivity.

The differences in the nature and physicochemical properties of environmental samples impact DNA yields, and therefore, an optimisation of the protocols is always recommended. For instance, samples collected from corroded areas contain high concentrations of metals, salts, and hydrocarbons that can ...
The two concepts have been successfully applied to develop a process for the separation of high purity cobalt and nickel from ocean nodules leach liquor. 展开 关键词: Mixed-metals isotherm Log-log McCabe Thieles diagram Ocean nodules Copper Zinc Cobalt Nickel DEHPA PC-88A Solvent extraction ...
We report parameter studies of the key processes of the method, which validate this concept and which define the parameters for the setup. This would allow for the first time the extraction of radioactive molybdenum, tungsten and several other transition metals at thick-target ISOL facilities....
Schematic diagram of SPE cartridge Full size image A brief history of SPE Due to its many advantages over other traditional methods, SPE was applied for the first time during the 1940s [6], and has quickly grown in many applications during the 1970s. Animal charcoal was probably the first ...
If this occurs, and the recovered alum is used for water treatment, it may cause a degradation of the potable water. The potential impurities include: (1) impurities capable of being converted to a soluble form in the acidulation process such as iron, manganese, chromium, other metals and ...
FIG. 1 illustrates the dissolution of two metals by the liquid cation exchanger. FIG. 2 shows the dissolution of zinc calcine by the organic phase, and subsequent transfer of zinc to the aqueous phase. FIG. 3 is a process diagram for recovery and separation of copper, zinc, and iron from...
