A solid agricultural waste, coffee husk, was applied as an adsorbent for reactive dye-polluted wastewater treatment. Coffee husk biochar was pyrolyzed at 450 °C and then chemically activated using 50% ZnCl2 solution. The surface of activated coffee husk biochar was modified using a cationic surfactant, Cetyltrimethylammonium bromide (CTAB), to create CTAB-modified coffee husk biochar (MCH), to improve reactive adsorption of anionic dyes from synthetic wastewater. The selected reactive dyes were reactive yellow 145 (RDY145), reactive red 195 (RDR195), and reactive blue 222 (RDB222). The adsorption kinetics fit well using a pseudo-second order model for all three dyes. The adsorption isotherms matched well with the Langmuir model .The removal efficiency of RDY145 (83.7%) was the highest, followed by RDR195 (71.1%) and RDB222 (59.6%). The amount of RDY145 adsorbed by MCH was about 9-fold that adsorbed by conventional activated carbon. Additionally, the solution pH had no effect on reactive dye removal efficiency using MCH.

“…There is not much change in the padded polyester since the intensity and position of absorption peaks were not changed too much. Cleary can be seen an absorption bend of C = O vibration is shifted to the left (1760 cm − 1 ), indicating the adhesion of acrylic acid on the surface, and it introduced carboxyl groups 14 . Covered polyester shown an absorption peak at 2957 cm − 1 assigned to stretching vibration of C-H groups, intensive band at 1449 cm − 1 is due to bending vibrations of -CH 2 groups; the band at 1162 cm − 1 corresponds to stretching vibrations of C-O-C, which indicates the self-cross-linking in the polymer composition on the surface of polyester due to the etheri cation of carboxyl groups.…”

Organic dyes such as Methyl Orange (MO) and Methylene Blue (MB) are widely used in different industries, becoming one of the leading emerging water contaminants. It is urgent to develop the most suitable materials for effective elimination of the dyes as they are non-biodegradable and are not removed efficiently by the traditional treatment methods. The present work applied polystyrene-acrylic/ZnO nanocomposite on the polyester surface by blade coating and one-bath pad methods. Features of surface chemical modifications were determined by FTIR, SEM analysis, WCA, N2 adsorption-desorption isotherms. The functionalised layer can create unprecedented function of filter textile material depending on the way of treatment. The possibility of using such fabrics as ﬁlters was explored for MO and MB in the concentration of 100 ppm. Water purification occurred by 60% from methylene blue and 40% from methylene orange flowing through the padded polyester filter and the covered polyester filter for 2 min, respectively. Moreover, it was shown that a colourless reduced form of MB – leuco-methylene blue (LMB) could be created. The functionalised layer of the developed filters through hydrogen bonding between the –OH groups of styrene-acrylic molecules and the –N(CH3)2 groups on LMB can stabilise LMB.

“…Recently, Eom et al [34] described the graphitization process of CNCs from 1000 to 2500 °C using spray pyrolysis methodology to obtain fiber structures. Moreover, rounded carbon particles have been successfully used for water purification and environmental remediation [35,36], composites production [37,38] and energy storage [39]. According to the great interest in the carbon shape tunability, we used CNCs as template for producing microstructured carbon species, ranging from spherical to needle-like structures.…”

Bioderived scaffolds are largely used as template for the synthesis of drugs and materials. Among biomass sources, cellulose has been used as platform for numerous conversions and applications. In this study, we report the use of crystalline microstructured cellulose as feedstock for microstructured carbon production. Different morphologies were produced according to pyrolytic conditions ranging from sphere, needle and carbon-on-carbon-decorated surfaces. All the materials were characterized using spectroscopic techniques (i.e., Raman, FTIR), FESEM and thermogravimetric analysis. Hypothetical reaction pathways were proposed for describing materials shape and properties. In particular, for cellulose nanocrystals, the thermal treatments induced noteworthy electrical properties that could be applied for the production of conductive composites.
