Abstract
Nanotechnology, whose
area of use is expanding every day with developing technology, is a
multidisciplinary field that deals with production, development and different
application areas of new materials referred to as nanoparticles (NP) in the
literature.
According to definition, nanoparticles, particles with sizes ranging from 1-100
nm, have superior qualities compared to counterparts as small particle size,
large surface area, resistance to UV light, antibacterial and antimicrobial
effect, and conductivity. Although nanoparticles can be synthesized by various
methods, the environmental and toxic effects of these methods have encouraged
the research of alternative environmentally friendly techniques. Green
synthesis has been used since the early 2000s and is an important method that
increases sustainability by reducing environmental impact. Green synthesis
methods also aim to reduce the amount of waste that may be generated or to
obtain useful products by evaluating waste. These approaches in green synthesis
processes allow chemical reactions in industrial processes to be carried out
both more efficiently and cleaner. Sophora
japonica L. is a perennial, deciduous, woody plant belonging to the genus
Sophora. Flowers, fruits, branches and leaves of S. japonica, an important plant with edible and medicinal
properties, have been used in traditional medicines for many years for
detoxification, lowering blood pressure and controlling bleeding. In this
study, calcium oxide (CaO) nanoparticles were synthesized using Japanese
sophora (Sophora japonica) fruit
extract by incubation method and in accordance with green synthesis. Characterization
of the synthesized nanoparticles completed by UV-VIS and ATR-FTIR spectroscopy,
XRD and SEM analyses. Antibacterial and antifungal activities of the
nanoparticles were evaluated and adsorption efficiency on the removal of Congo
Red dye, an environmental pollutant investigated. Biological activity results
showing that nanoparticles are an efficient alternative, it was also determined
that they provided high-efficiency dye removal for a long time up to 24 hours. Findings
revealed that CaO nanoparticles prepared via green synthesis are a sustainable
option for environmental and biomedical applications. Dye removal studies
showed that these nanoparticles can be used with high efficiency in
environmental treatment systems.
