Developed Method for Spectroscopic Studies of Viscous Samples

“…Therefore, the samples that have viscosity less than or equal to 1.136 mm 2 =s can be successfully injected and analyzed with FAAS and ICP-AES Figure 6 shows the ultraviolet-visible (UV-vis) spectra of different concentrations of phosphoric acid in aqueous solution. The absorption band appeared at 228 nm at high concentration (8.5%) may be due to the electronic transition p-p à (Paredes, Ponce, and Moller (2006). The shoulder appearing at 275 nm is assigned to electronic transition n-p à or (O !…”
