Web5 Oct 2024 · Absorption bands characteristic of barite can be observed in the concentrate’s spectra. The spectra contain also other absorption bands related to carbonates and silica present in minor proportions. However, the spectrum of the obtained tailings contains carbonates and quartz with minor proportions of barite.

WebAbsorption band tailing Absorption tail breadth is known to be determined by the tail breadth of the density of electronic states.1 Absorption tail is usually described by a linear-exponential function 𝐴(ℎ𝑣)=𝐴0 ( ℎ𝑣− 0/ 0) where A0 and hv0 are numerical constants, and E0 is referred to as the absorption tail breadth.2 Web19 Nov 2013 · The presence of aromatic rings and conjugated π systems, as well as various functional groups and heteroatoms, facilitate the direct absorption of solar radiation. 9 Such structures result in strong absorption in the UV-C wavelength range, with tailing absorption into the UV-B and in some cases UV-A ranges.
