Abstract
Green synthesis, an eco-friendly and sustainable approach, is becoming popular for
nanoparticle production. This method minimizes the use of hazardous chemicals, making
it a desirable alternative for various applications. The current study focuses on
synthesizing green TiO2 NPs using Kigelia africana leaf extracts (sausage tree)
and evaluating their performance in photo-catalytic treatment of textile wastewater
post-secondary treatment. The TiO2 NPs using Kigelia africana leaf extracts resulted
in nanoparticles characterized by several advanced techniques, confirming their
morphology, structure and composition. The synthesized TiO2 NPs were tested for
their efficiency in treating textile effluent, specifically targeting the removal
of organic dyes. SEM images revealed the morphology and size of the TiO2 NPs. The
nanoparticles were confirmed to be spherical in shape. EDX analysis provided the
elemental composition of green synthesized TiO2 NPs. Presence of titanium and oxygen
elements was confirmed, validating the synthesis process. XRD patterns confirmed
the crystalline structure of the TiO2 NPs.
The nanoparticles exhibited the anatase phase known for its superior photo-catalytic
properties. FT-IR spectra identified the functional groups involved in the synthesis.
The presence of characteristic TiO2 peaks was observed, indicating successful formation
of TiO2 NPs. DLS measurements provided information on the particle size distribution.
The synthesized nanoparticles had a narrow size distribution, confirming their uniformity.
TEM images further confirmed the spherical shape and size of the TiO2 NPs. High-resolution
images showed well-defined and uniformly distributed nanoparticles. The photo-catalytic
treatment achieved a 98.69% removal of Toludine Blue (TB) dye within 65 minutes.
This high efficiency demonstrates the potential of green-synthesized TiO2 NPs in
treating organic dyes in textile wastewater.
