Metal biosorption onto non-living algae: a critical review on metal recovery from wastewater

Abstract

The widespread occurrence of metals in water bodies has been fueling the development of platforms for removing and recovering these elements. Biosorption has emerged as a potential tool for metal...

Adsorption of Toxic Cd(II) on an Antibacterial Biopolymeric Gel toward Fabrication of a Gel Electrolyte-Based Supercapacitor Device

“…The effluent water generally contains biological, inorganic, and organic pollutants, which is directly or indirectly mixed into the water bodies, making them contaminated . Inorganic heavy metals (such as Cd 2+ , Cu 2+ , As 3+ , Pb 2+ , Zn 2+ , Hg 2+ , Cr 6+ , Ni 2+ , and Co 2+ ) are the most frequently discharged pollutants, which are highly toxic, carcinogenic, and nonbiodegradable in nature. , These ions can transmit through the food chain and accumulate in the living organisms as well as in the human body . Cd 2+ ions are considered one of the major toxic pollutants if they persist in industrial wastewater .…”
