The UV-Vis spectral properties of the elaborated structure as well as its spectral response to the pH are investigated in detail. The results show that the present THPBA, combining carboxyl, azo, and multihydroxyl groups, possesses excellent UV-vis spectra (εmax = 2.794 × 10–2.115×10 L...

The goal of this study was to develop a method that uses UV-Vis spectroscopy for the determination of residual polymer concentration water and environmental samples. UV-Vis absorbance measurements are quick and simple and can be usefully applied in research and practice. Five different polymers exhib...
We demonstrate the validity of the Beer-Lambert law for PTANa, PTAA/Na, and PTAA/Li (aged solution), and violation of this law for PTANa/Me (fresh) solutions in water; the latter system is instead found to exhibit an isosbetic point at 402 nm. We prove that UV/Vis spectra of ...
