A review on advances and mechanism for the phycoremediation of cadmium contaminated wastewater

Modification of silica nanoparticles by 2,4-dihydroxybenzaldehyde and 5-bromosalicylaldehyde as new nanocomposites for efficient removal and preconcentration of Cu(ii) and Cd(ii) ions from water, blood, and fish muscles

“…[1][2][3] Cadmium and its compounds are highly toxic where exposure to them causes cancer and damages the cardiovascular system, digestion, breathing, reproductive system, kidneys, and nerves. [4][5][6] Excess amounts of copper may cause liver and brain poisoning, diarrhea, skin rashes, anemia caused by red cell breakage, high blood pressure, heart disease, premenstrual syndrome, nausea, stomach pain, and severe damage to the central nervous system. Excess amounts of copper also accompany psychological and mental illnesses such as autism, behavior problems, hyperactivity in children, depression in adults, dementia, and stuttering.…”

A Sustainable and Cost‐Effective Bioadsorbent for the Removal of Allura Red from Contaminated Water

“…Azo dyes are very recalcitrant and stable to oxidizing agents [24,25] Various physical, chemical and biological methods have been used for the treatment of wastewater with their own limitations and disadvantages. [26][27][28][29] Adsorption is considered to be the low-cost, simplest and effective method for removing coloring impurities from wastewater. AR is a very less explored dye with respect to its removal; few researchers have studied its removal from wastewater using adsorption and other techniques.…”

Interpretation of the adsorption process of toxic Cd2+ removal by modified sweet potato residue

“…4 Removing Cd from wastewater is therefore critical to meet effluent standards before it can be discharged. 5 Various physical, chemical, and/or biological approaches have been developed to remove heavy metals from wastewater, such as photocatalysis, electrochemical treatment, ion exchange, coagulation/occulation, nanoltration, and adsorption. 6 Among the reported approaches, adsorption, including physical and chemical adsorption processes, has been considered as one of the easiest and most cost-effective techniques because of its strong adaptability in removing various heavy metals from aqueous solutions with simple operation.…”
