Anion exchange separation and spectrophotometric determination of titanium in uranium-plutonium ternary alloys

An Optical Fiber ${\rm H}_{2}{\rm O}_{2}$-Sensing Probe Using a Titanium(IV) Oxyacetylacetonate Immobilized Nafion Coating on an Bent Optical Fiber Probe

“…The results shown in this graph clearly demonstrate the response of the sensing probe to trace in the water sample. The peak absorption wavelength (360 nm) observed in this work is blue-shifted compared with the peak absorption wavelength of complex formed in acidic aqueous solutions, which is 410 nm, [22]. An explanation for this blue-shift of peak absorption wavelength is that the concentration of in the water sample tested in this work is in ppm level.…”

“…The formation of yellow titaniumoxo hydrogen peroxide complex, , has been used for detecting in aqueous solutions in traditional UV/Vis absorption spectrometric methods [22]. This complex is formed in an acidic solution with the existence of excess in an aqueous solution.…”

“…This complex is formed in an acidic solution with the existence of excess in an aqueous solution. The formed complex absorbs light with peak absorption wavelength at around 410 nm [22].…”
