Using nano-magnesium oxide/bentonite composite for cadmium removal from industrial wastewater

نویسندگان

چکیده

Nowadays, the removal of toxic heavy metals from industrial wastewater is a long standing problem due to progress worldwide. This study mainly focused on production novel nMgO-bentonite nanocomposite using sol–gel method enhance Cd ions wastewater. The nano-composite was characterized for structural morphology and presence functional groups SEM/EDS, XRD FTIR analysis. Cadmium sorption equilibrium kinetic data were well fitted Langmuir power function models respectively as confirmed by highest R2 (0.965), lowest SE (38*10-6) values among other studied models. capacity 200 mg/g which 60 times greater than that bentonite. Increased with increased temperature 287 307K thermodynamic results revealed adsorption process endothermic spontaneous. also showed highly repetitive application during six cycles adsorption/ desorption experiment. final pointed out has great affinity could potentially employ cost-effective, ecofriendly efficient sorbent contaminated

Phosphorus Removal from Domestic Wastewater Using Engineered Nano-media

Dissolved, bioavailable phosphorus originating from onsite and municipal wastewater is being recognized as one of the contributors to eutrophication and, more recently, high profile cyanobacteria incidents. This has resulted in very low regulatory limits in some regions, well below 1 mg/L, which are very hard to economically and reliably reach with conventional biological and chemical treatment...
