One-step synthesis of highly porous carbon graphite/carbon nanotubes composite by in-situ growth of carbon nanotubes for the removal of humic acid and copper (II) from wastewater

Preparation of Ultrafiltration Membrane by Polyethylene Glycol Non-Covalent Functionalized Multi-Walled Carbon Nanotubes: Application for HA Removal and Fouling Control

“…Their relative TMP (P−P 0 ) slowly increased at the beginning and then tend to be stable. As reported, MWCNT has strong adsorption capacity, it has very high removal effect on HA [ 45 , 46 ]. Sabrine et al [ 39 ] prepared porous carbon graphite/multi-walled carbon nanotube composite materials by growing multi-walled carbon nanotubes in situ on porous carbon materials, which effectively improved the adsorption capacity of HA.…”

Carbon nanomaterials for the treatment of water pollutant in the purpose of environmental remediation

“…Since carbon nanotubes (CNTs) were discovered [3], they have been considered an attractive material for nanotechnology applications such as adsorbent for environmental remediation [1]. Although, a large variety of methods have been developed to remove persistent organic pollutants from wastewaters which include adsorption process [4,5]. In view of the health problems caused by humic substances, the present work describes the adsorption behavior of humic (HA) acid onto carbon composites materials.…”

“…, was chosen based on our previous research works[4]. Novolac ® type phenolic resin dissolved in an ethanolic solution was added in separate doses to the mixture of graphite powder, avicel ® , ethylene glycol and ferrocene.…”

“…Different steps of the process developed for the preparation of porous carbon composite2.3. Adsorption of humic acid (HA)The adsorption tests were carried out by immersing the carbon composites (40 mm length × 10 mm width × 3 mm thickness) in 50 mL of HA (50 mg/L) aqueous solutions, under stirring at room temperature[4]. The adsorption percentages of organic pollutants were calculated as follow:…”

Mechanism and Kinetics of the Thermal Decomposition of Fe(C5H5)2 in Inert and Reductive Atmosphere: A Synchrotron‐Assisted Investigation in A Microreactor

“…[9,10] Those Fe-NPs have additionally shown excellent performance and emission characteristics in biodiesel engines [11,12] and as a burning catalyst in rocket propellants, [13] since hydrocarbon radicals, responsible for soot formation, are quenched. [11] Nowadays, ferrocene is among the most widely used precursors in the synthesis of carbon nanotubes (CNTs), [14] either as a feedstock to produce catalytic sites necessary for their growth, [15][16][17][18][19][20][21][22] or as both carbon and catalyst precursor. [23][24][25][26] Those functional nanomaterials are often manufactured by high yield, low-temperature methods, [14] as for instance by catalytic chemical vapor deposition (CCVD).…”
