Insight into the Adsorption Properties of Chitosan/Zeolite-A Hybrid Structure for Effective Decontamination of Toxic Cd (II) and As (V) Ions from the Aqueous Environments

Insight into the synergetic, steric and energetic properties of zeolitization and cellulose fiber functionalization of diatomite during the adsorption of Cd(ii): advanced equilibrium studies

“…10,12 The pollution of water resources with Cd(II) has been detected widely and is caused essentially by the discharged effluents from numerous industries (smelting, cadmium-nickel batteries, metal plating, pigments, and alloys). 13,14 The Cd(II) was classied as a carcinogenic and very toxic chemical ion that must be at a concentration lower than about 0.003 mg L −1 in the drinking water. 4,15 Moreover, the Cd(II) pollutants cause several health side effects, such as acute disorders, pulmonary edema, chronic disorders, emphysema, itai-itai disease, hepatic dysfunction, hypertension, testicular atrophy, osteomalacia, and renal damage.…”

“…17 Moreover, the unacceptable concentrations of Cd(II) cause strong adverse effects on aquatic life and ecosystems, as well as the economic quality of sh. 14 Therefore, the effective elimination of the Cd(II) concentration in the water supplies is a critical concern considering the previous reported environmental and health hazards. The adsorption decontamination of dissolved metal ions such as Cd(II) by natural and synthetic adsorbents was recommended in numerous studies as a simple, effective, simple, and low-cost purication technique.…”

Insight into the adsorption properties of a β-cyclodextrin/phillipsite organophilic composite for effective removal of toxic organophosphorus pesticides: kinetic and advanced equilibrium studies

“…11,15 Synthetic zeolite/biopolymers were introduced recently as potential multifunction adsorbents that exhibit remarkable adsorption capacity, recyclability, biodegradability, ion exchange capacity, and environmental values. 16,17 Natural zeolite phases as well as their composites have been reported as promising adsorbent materials during the decontamination of organic and inorganic dissolved chemicals. 18,19 Natural zeolites as a nanoporous material exhibit a unique surface area, surface reactivity, adsorption capacity, chemical stability, and environmentally safe properties.…”

Water decontamination in terms of Hg(II) over thiol immobilized magnesium ferrite: Gum Arabic biosorbent—response surface optimization, kinetic, isotherm and comparing study

“…Mercury is a high reactive and volatile metal that is relatively soluble in living tissues and water resources hence it can causes damage to kidney and nervous system as well as birth and chromosome defects [3,4]. Mercury thrown in environment has been increased dramatically in recent decades owe to extensive development in textile, fertilizer, leather and military industry [5][6][7].…”
