Synthesis and characterization of mango leaves biosorbents for removal of iron and phosphorous from contaminated water

Removing Heavy Metals: Cutting-Edge Strategies and Advancements in Biosorption Technology

“…Over time, these binding sites can become saturated as the biosorbent accumulates pollutants, decreasing its capacity to sorb additional contaminants. For example, as shown in the work on the removal of iron and phosphorus from a model solution by mango leaf biosorbents [ 92 ], the deactivation of biosorbents is attributed to the reversible or irreversible chemisorption of iron and phosphorous molecules to active sites. This reduces the number of sites available for the adsorption reaction.…”

Green chemistry: advancing planetary phosphorus sustainability through the synergy of graphene oxide modified with magnetic nanoparticles (M@GO) for extracting tertiary effluent phosphorus in sewage treatment plants

“…Phosphorus is used in detergents, toothpastes, fireworks, and in the heads of matches. 1 Phosphorus (P) together with nitrogen (N) and potassium (K) is a biolimiting nutrient for plants, being included as a chemical constituent of fertilizers. 2 Phosphate is necessary for plant growth.…”

Recent advances in the biosynthesis of ZnO nanoparticles using floral waste extract for water treatment, agriculture and biomedical engineering

“…11 The mass discharge of ower waste into rivers signicantly impacts the ora, fauna, and overall aquatic ecosystems. 12 This waste, originating from oral and religious sites; social events such as birthdays, weddings, and funerals; and recreational venues such as hotels and spas, raises signicant concerns. 13 Every year, millions of tons of dried owers from major religious sites globally nd their way into rivers or become part of solid municipal waste.…”

“…As owers enter water bodies, they elevate biological oxygen demand and worsen various wastewater indicators. 12 Moreover, the presence of pesticides in owers leads to the introduction of unwanted pollutants into water bodies, significantly compromising the water quality. 15 Discarded owers in open areas become breeding grounds for mosquitoes and other insects, thus emitting foul odors, polluting the land, and drastically diminishing the visual and aesthetic appeal of the surroundings.…”
