Role of Phytonanotechnology in the Removal of Water Contamination

Abstract

Environmental pollution is expedited by the rapid increase in population, urbanization, industrialization, and growth in the global economy. Water contamination is accelerated by the incautious disposal of wastes into water bodies. The need of the hour is to develop novel, ergonomic, subsidized, and reproducible technologies that assist in the remediation of such wastes that require minimal human intervention, preserve the quality of water, and are eco-friendly. Phytonanotechnology is emerging as a promising strategy, characterized by the biosynthesis of metallic nanomaterials and nanoparticles (NPs) using plant-based sources. Conventional remediation technologies like adsorptive, reactive, in situ, ex situ, and open fabrication of phytogenic magnetic NPs (PMNPs) have already been established in scientific literature. A keen understanding of building material platforms, fabricating and performance-optimizing are required to develop nanomaterials capable of addressing environmental issues. Furthermore, their antimicrobial activity, biodegradability and biocompatibility, optoelectronic properties, low toxicity, availability, energy efficiency, and versatility have been utilized efficiently.

A pragmatic review on photocatalytic degradation of methyl orange dye pollutant using greenly biofunctionalized nanometallic materials: A focus on aquatic body

“…Ulva lactuca seaweed extract was used by Gole et al 251 to biogenically create a highly potent and durable green Ag NPs photocatalyst. By using HR‐SEM, it was determined that the spherically shaped NPs had an average size of 48.59 nm.…”

“…Using silver nanocatalysts and sun irradiation methods, the photocatalytic degradation of the MO dye was studied at various time intervals. Within 12 h of the incubation period, a drop in peak intensity allowed researchers to confirm dye degradation 251 …”

“…This research team carried out the biofabrication of Ag using rind extract of Citrus aurantium, and the photocatalytic activity of this photocatalyst revealed its efficiency to be just 51% in 4 h under sunlight irradiation. 250 Ulva lactuca seaweed extract was used by Gole et al 251 to biogenically create a highly potent and durable green Ag NPs photocatalyst.

Insights into the recent advances in nano-bioremediation of pesticides from the contaminated soil

“…Phyto-nanotechnology is an efficient, cost-effective and eco-friendly strategy, which is extensively used for the remediation of toxic compounds from the ecosystem ( Gole et al, 2022 ). This technology involves the plant based synthesis of nanoparticles with almost no risk to the ecosystem and humans.…”
