In this work, the degradation of Basic Red 29 (BR29), an azo dye, was investigated using a high-frequency ultrasonic reactor (300 kHz). The influence of several parameters such as initial substrate concentration (5–200 mg L−1) , pH (3–10.1), ultrasonic power (20–80 W), and nature of the dissolved gas (Ar, air, and N2) on the degradation of BR29 was assessed. Additionally, the impact of natural ...

Natural dye-sensitized solar cells (NDSSCs) have gained considerable attention in the field of solar energy due to their simple fabrication, good efficiency, and low production cost. Natural dyes are environmentally and economically superior to ruthenium-based dyes because they are nontoxic and cheap. However, the conversion efficiency of dye-sensitized solar cells based on natural dyes is low....

Abstract Dye-Sensitized Solar Cells (DSSC), a 3rd generation solar cell has gained huge attention in the field of photovoltaics as substitute for silicon cell. The performance DSSC mainly depends on all important components such transparent conductive oxide substrate, cathode, photo-anode, dye, and electrolyte. Additionally, sensitizing dyes also perform vital role absorption light conversion e...

In recent years, chitosan and its different derivatives have been extensively used in surface modification and functional finishing of textiles. In this study, wool yarns used in handmade carpet were treated with different concentrations of chitosan-poly (amidoamine) dendrimer hybrid (Ch-PAMAM) and characterized by scanning electron microscope (SEM), and their dyeing properties were investi...

The photocatalytic degradation of methylene blue was investigated with TiO2 and Fe2O3 nanoparticles supported on natural zeolite. The synthesized photocatalyst was characterized by XRD, XRF, FT-IR, EDX, FE-SEM, and BET analyses. The results of XRD, FT-IR, and EDX confirmed the successful loading of Fe3+ doped TiO2 nanoparticles on natural zeolite. Further, the FE-SEM results confirmed the depos...

this study presents the natural dye recovery from various biodegradable temple and household wastes. the raw material for colour extraction consisted residual flowers and garlands from various temples as well as onion and vegetables peels from vegetable markets, university hostels, and households, which were washed, dried, crushed, and sieved. the extracted natural colours were produced by mean...

Introduction: Dyes have complicated structures, they are usually toxic and resistant to biological treatment and enter the environment through industrial waste streams. The aim of this study was to review the isotherm and kinetic adsorption studies of Reactive Blue 19 (RB19) dye onto Jujube stems powder from synthetic textile wastewater. Materials and Methods: This study was conducted in labo...
