Development of sodium alginate@ZnFe-LDHs functionalized beads: Adsorption properties and mechanistic behaviour of phosphate and nitrate ions from the aqueous environment

Phosphate and nitrate are the vital micro-nutrients and a substantial contributor to the growth of biomass, energy storage, and agricultural activities. However, in their increased concentrations, they also cause potential health problems to human and all other living beings. Layered double hydroxid...
