Fast and effective removal of Pb(II), Cu(II) and Ni(II) ions from aqueous solutions with TiO2 nanofibers: Synthesis, adsorption-desorption process and kinetic studies

APTMS-BCAD modified magnetic iron oxide for magnetic solid-phase extraction of Cu(II) from aqueous solutions

“…Because the active sites are bigger and more scattered in the early phases of adsorption, this result shows that toxic metal ion adsorption is faster. This is in line with our previous work and literature [ 25 , 70 , 71 ]. As a result, the contact time of 120 min was chosen for other adsorption experiments.…”

“…Nanocomposite materials are known as more efficient and attractive sorbents due to their multifunctionality in sample preparation techniques. Nanomaterials such as carbon-based sorbents [ 19 , 20 , 21 ], low-cost lignocellulosic substrates [ 22 , 23 ], metal oxide composites [ 24 , 25 ], and mesoporous silica [ 26 , 27 ] have attracted attention to removing heavy metal ions. Magnetic nanoparticles (MNPs), especially with superparamagnetic properties, are frequently used in MSPE techniques for the concentration, departure, and removal of diverse analytes [ 28 ].…”

Removal of lead from aqueous solution using electrospun nanofibers: preparation, characterization, adsorption isotherm, and kinetic study

“…To better understand the dynamics of the solid-solution interface during the adsorption of Pb( ii ) from the aqueous solution, models can be utilized. 49 Adsorption kinetics is the theoretical basis that determines the time required to set up the adsorption balance. Examining the adsorption kinetics is an important step to understand the adsorption steps that affect the rate of the adsorption process.…”

Facile Synthesis of Fiber‐Reinforced Catalyst for High Performance Ethanol and 2‐Propanol Oxidation

“…The obtained TiO 2 nanofibers were calcined at 500 °C for 60 min at a temperature increase rate of 5 °C min À1 in an atmospheric environment. [29] Synthesis of Electrocatalysts: The synthesis of electrocatalysts used in alcohol oxidation studies was carried out using the sodium borohydride chemical reduction method. In this context, firstly, 10 mM PdCl 2 and 40 mg calcined TiO 2 fiber were kept in 20 mL dH 2 O for 30 min in a magnetic stirrer and 30 min in ultrasonication.…”
