This study investigates the removal of ibuprofen and diclofenac from aqueous media via a fully pressurized dissolved air flotation system, enhanced by fenugreek-derived saponin, a plant-based biosurfactant. The use of fenugreek saponin in flotation processes distinguishes this work from previous studies as it offers an ecofriendly and efficient alternative to chemical surfactants. The biosurfactant's surface-active properties were confirmed through FT-IR, UV-vis spectroscopy identified key functional groups and structural characteristics of the saponin, NMR provided molecular insights into its bioactive components, and surface tension analyses demonstrated its ability to reduce interfacial tension, indicating effective surfactant behavior.

Degradation of tartrazine dye (TZD) was performed in this study using sulfate radicals (SO) generated from the activated sodium persulfate (SPS) using FeO@PDA nanoparticles (NPs). The NPs were characterized by Fourier transform infrared (FTIR), vibrating sample magnetometer (VSM), X-ray diffraction (XRD), high-resolution scanning electron microscopy (HR-SEM), X-ray photoelectron spectroscopy (XPS), high resolution transmission electron microscopy (HRTEM), and energy-dispersive X-ray spectroscopy (EDX). The average particle size of the NPs was 17.

Evaluation of arterial stiffness is significant in early detection and vascular diagnosis. We have developed and validated an image free system called ARTSENS for evaluation of carotid artery stiffness. In this paper, we present a detailed study on the repeatability of arterial stiffness measurements performed using ARTSENS.
