Adsorption of Cu2+ ions using chitosan-modified magnetic Mn ferrite nanoparticles synthesized by microwave-assisted hydrothermal method

New insight into electrochemical-induced synthesis of NiAl2O4/Al2O3: Synergistic effect of surface hydroxyl groups and magnetism for enhanced adsorptivity of Pd(II)

“…Then this experiment was conducted by adding 0.03 g of adsorbent in 250 mL beaker containing 150 mL of various concentrations of Pd solution (10-100 mg L −1 ). The sample pH (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12) was adjusted to the desired value with 0.1 M NaOH and 0.1 M HCl. The solutions were stirred at 400 rpm using magnetic stirrer to reach equilibrium.…”

“…In contrast, great interest has also been devoted to the extraction and recovery of this precious metal because of the increasing industrial demand and its limited resources [2]. Accordingly, several technologies have been developed for the effective removal of Pd ions from industrial wastewater, such as chemical precipitation, solvent extraction, electrolysis, membrane filtration, ion exchange, and adsorption [3]. However, most of these methods require high capital cost and energy consumption.…”

Mussel inspired preparation of amine-functionalized Kaolin for effective removal of heavy metal ions

“…As the increasing development of economy, the demand of water increasing and the problem of water pollution has become more serious. Heavy metal pollution, defined as a kind of environment pollution resulting from heavy metals or their compounds, is one of the most serious water pollution [2]. Due to its bioaccumulation and toxicity, heavy metal pollution has made seriously effect on ecosystems and human beings [3,4].…”

Preparation of Er3+:Y3Al5O12/KNbO3 composite and application in innocent treatment of ketamine by using sonocatalytic decomposition method

“…Therefore, for confiscated narcotic drugs the effective destruction and treatment technologies are very necessary. Some traditional treatment methods of narcotic drugs were most often used in many country [4][5][6][7][8]. However, these technologies have still exhibited many disadvantages or limitations [9,10].…”
