Abstract:
The excess in release of phosphates into aquatic ecosystems from various human sources
has caused widespread eutrophication creating significant environmental challenges. In response
to this issue, our study aims to address it by developing a new approach to recover phosphates
from eutrophic water through the use of functionalized biochar. This recovered phosphate can then
be utilized as a fertilizer for plant growth. Our method involves modifying biochar derived from
sugarcane bagasse with specific functional groups capable of capturing and retaining phosphate
ions efficiently. To analyze the characteristics of the modified biochar, we employed scanning
electron microscopy, X-ray diffraction, and Fourier transform infrared spectroscopy techniques.
The results demonstrate that using 4 g/L dosage of biochar achieves an optimal adsorption capacity
of around 80.25%. By providing a sustainable and integrated approach to phosphate recovery and
simultaneously addressing water pollution issues our study offers both an effective solution and a
valuable resource for agricultural applications. Incorporating functionalized biochar as a P based
fertilizer provides an encouraging avenue for sustainable agriculture practices. By decreasing
dependence on conventional chemical fertilizers and addressing concerns related to phosphate
pollution it offers an effective solution. Further research could potentially emphasize the
optimization of the synthesis process as well as the expansion of production at a larger scale, and
find the significant impacts of utilization of bio char on health of soil, its nourishment, and
sustainability of ecosystem.
