Characterization and evaluation catalytic efficiency of NiFe2O4 nano spinel in removal of reactive dye from aqueous solution

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.…”

“…NiAl 2 O 4 is commonly used as a supporting catalyst for various metals and oxides, particularly for gas-phase catalytic reactions, as well as a potential material for internal reforming solid oxide fuel cell anodes. However, some works have reported the difficulty of reducing NiAl 2 O 4 spinels for enhanced methanation [10]. This drawback has prompted researchers to find alternative uses for NiAl 2 O 4 .…”

Removal of hydrolyzed Reactive Black 5 from aqueous solution using a polyethylenimine–polyvinyl chloride composite fiber

“…In addition, adsorption process is more economical than other traditional processes [9]. In general adsorption efficiency depends on physical characteristics of adsorbents such as surface area, surface charge, sorbent size, porosity, and density of specific functional groups [10]. Thus, we need to develop a powerful adsorbent with high efficiency by comprising of various compositions, properties and functionalities for removal of toxic pollutants and production of clean water.…”
