“…TheRaman spectra of ACs with D band (~1320 cm −1 , ring breathing mode from sp 2 carbon rings, A 1g mode) and G band (1592 cm −1 , planar configuration sp 2 bonded carbon with bond-stretching motion, E 2g mode) of ACs. The ratio of the intensities of the D and G band is 0.91 for the AC 10. Moreover, the intensity of the D band is higher than the G band which indicates the AC is amorphous in nature.…”

“…For commercial carbons, Iodine number ranges from 300 to 1,200 mg/g. Phenol number and Methylene blue number indicate the ability of an adsorbent to adsorb high molecular weight substances like dye molecule 17 . Methylene blue number of (NAC 2 and NAC 5 ) is greater than 200, which indicates that the carbon is good for dye adsorption.…”

Textile effluents are one of the main sources of severe pollution problems worldwide due to vast diversity of chemicals reagents used by textile industries for various production steps. The discharge of dye containing effluents into fresh water bodies is undesirable because of the color. In the present work, activated carbon was prepared from the leaves of Azdirachta indica (Neem) by nine different carbonization processes. The effect of pH on the adsorption of four classes of dyes namely acid dye (Acid blue 49), basic dye (Basic red 29), reactive dye (Reactive orange 4) & direct dye (Direct blue 53) was studied by activated carbon (NAC 2 ), prepared from Neem leaves by H 3 PO 4 impregnation method. The effect of pH on the adsorption of four classes of dyes is discussed and the adsorption properties of activated carbon are evaluated. Effluent samples from textile dyeing effluents were also treated using the selected activated carbon. From the present studies, it has been evaluated that the activated carbon prepared from Azadiarchta indica (Neem leaves) could be used an efficient low-cost alternative to the commercial activated carbon.

“…Many have been classified as hazardous pollutants because of their potential harm to human health. 6,7 Phenolic compounds are widely found in the wastewaters from pesticide, pharmaceutical, petroleum, petrochemical and other industries. 1,2,5 The removal of phenolic compounds from wastewater before discharge into water bodies is a necessity in order to reduce their side effects on the environment and human health.…”

Macroporous nanocomposite of poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) and acid modified bentonite was prepared by radical suspension copolymerization. Nanocomposite was functionalized with diethylenetriamine (DETA), by ring-opening reaction of the pendant epoxy groups. Functionalization was performed in order to enable phenol derivatives sorption. This new, not sufficiently investigated material, with developed porous structure was denoted CP-S A -DETA. In this study, the influence of temperature on 4-nitrophenol (4NP) sorption on CP-S A -DETA was investigated. The chemisorption was estimated as dominant process since activation energy of sorption of 4NP of 54.8 kJ mol -1 was obtained. After determining the optimal sorption conditions for 4NP, the sorption of 2-nitrophenol (2NP) and 2-chloro-4-nitrophenol (2Cl4NP) on CP-S A -DETA was investigated with respect to pH, initial concentration and contact time. The 2NP sorption was seldom tested, while according to our knowledge, the 2Cl4NP sorption was not investigated. The isotherm data were best fitted with Langmuir model, while the sorption dynamics obeyed the pseudo-second-order kinetic model for all derivatives.
