General requirements adsorbent adsorbent: large surface area and a certain adsorption capacity. Not from chemical changes and the agent does not respond or catalytic substances to be separated, decomposition or association, uniform particles. 1. Silicone dioctyl polar sorbent quotes, alumina adsorbents are polar, characterized by: a) for polar substances with strong affinity and capacity, strong polar solute is preferentially adsorbed. b) less polar solvent, the solute will adsorbents showed strong adsorption capacity. Solvent polarity increased, the adsorption capacity of the adsorbent for solute weakens. c) even if the solute is adsorbed to silica gel, alumina, but once the solvent was added polar GB dioctyl can be replaced by the latter eluted. Polar strength of judgment (and functional groups of species, of the number and arrangement of the way): polar proportional lipophilic groups and inversely proportional to the polar hydrophilic groups; free weakly polar compounds, with lipophilic, strong dissociative polar compound, is hydrophilic; polar solvents - to decide based on the dielectric constant. Nature and atomic structure atomic spectral line system is closely related, is an important basis for study of atomic structure. Principles and experimental methods can be applied spectroscopy spectroscopy dioctyl spot, each element has its unique identity lines dioctyl bright line spectrum to identify spectral lines of a substance produced and known elements Compare these substances can know which elements are made, with the spectrum not only qualitative analysis of the chemical composition of the material, and can determine how many elements content. Spectroscopic method has high sensitivity and accuracy. By spectral analysis in geological exploration can test the ore contained trace amounts of precious metals or radioactive elements and other rare elements. By spectral analysis speed, greatly improving the work efficiency. You can also use the spectroscopic study of the chemical composition of objects as well as standard prototype calibrated length and so on.
