“…High porosity of carbon allows for high adsorption capacity, thus making it an effective material for oil-water separation. 32,33 In this work, porous carbon was synthesized using the hydrothermal-carbonization method, with polystyrene particles dispersed in a cellulose nanober mixture as the matrix. Characterization of the carbon monolith (CM) were performed to determine the optimal ratio of TEMPO-oxidized cellulose nanobers (TOCN), polystyrene latex (PSL), and Pluronic F-127 (PF 127), as well as the carbonization temperature of the hydrochar on the pore structure.…”

“…This is one of the most important factors to evaluate the adsorption capacity of activated carbon. It is commonly known that comparatively more active sites are available on a wider surface, allowing the material to be promising for adsorption 52,53 . In the present work, the BET surface area and total pore volume of ACTG were obtained as 1270 m 2 /g and 0.673 cm 3 /g, respectively.…”

High quality activated carbon was successfully produced from Tectona grandis sawdust by chemical activation using potassium chloride and sodium thiosulphate in a ratio of 1:1.5:1. Surface characterization of sawdust and activated carbon showed the presence of several functional groups such as hydroxyl, ketones, phenols, carboxylic acids, aldehydes and aryl halide together with the heterogeneous surface and extensive porous network as depicted by morphological characterization. It was found that the per cent yield by mass of Tectona grandis sawdust was 52% (SD ± 0.41%). The content of fixed carbon (67.3%) and volatile matter (13.7%) in T. grandis sawdust signifies the ease with which it can be ignited and oxidized. The x‐ray diffraction analysis of activated carbon prepared from T. grandis sawdust indicated amorphous behavior of activated carbon. In the present work, activated carbon possesses 8.76 pH zero‐point charge, 1270 m2/g BET surface area, 0.673 cm3/g total pore volume and 0.42 g/cm3 bulk density.

“…The diameters of the nano zero-valent iron prepared from Marjoram supported on bentonite (Mar-nZVI Bent) were in the range of 37.77 nm -115.3nm compared with 51.32nm -87.94nm in nano zero-valent iron prepared from Moringa (Mor-supported on bentonite (Mor-nZVI Bent) ( Figure 2, E, F). Methods such as scanning electron microscopy (SEM), in view of their ability to directly view the micro-structure of activated carbons have demonstrated enormous potential for use in the study and characterization of activated carbons [Achaw and Afrane, 2008].Several research studies the role of Ach and Bent for remediation of pollutants from water (Amorim et al, 2013 andRajak et al, 2018). The analysis of electron microscopy shows that the formed nanoparticles of nano zero-valent iron prepared from Marjoram (Mar-nZVI), and B, zerovalent iron prepared from Moringa (Mor-nZVI) were circular shapes and sizes.…”

The preparation of eco-friendly low-cost activated charcoal (Ach),bentonite (Bent), nano zero-valent iron prepared from Marjoram (Mar-nZVI), nano zero-valent iron prepared from Moringa (Mor-nZVI), Mar-nZVI .Ach, Mar-nZVI. Bent, Mor-nZVI. Ach, and Mor-nZVI. Bent with and without Plantago major for the removal of flonicamid pesticide from aqueous solution has been investigated. Structure and morphology of Ach, Bent, Mar-nZVI, Mor-nZVI, Mar-nZVI.Ach, Mar-nZVI.Bent, Mor-nZVI.Ach and Mor-nZVI.Bent were characterized by UV spectroscopy , Fourier transform infrared spectroscopy (FTIR), Highresolution transmission electron microscopy (HRTEM), field emission scanning electron microscopy (SEM). The results showed that, Mar-nZVI .Ach, Mar-nZVI .Bent and Ach have faster flonicamid removal at all treatment periods. The percent removal of flonicamid in the water reached 31.81%-99.42 by Mar-nZVI.
