“…The solid form 13 C NMR spectra were obtained from crosspolarization (CP) with the magic angle of rotation spinning (MAS) technique in a Bruker AC 300 spectrometer, at room temperature, in a powder disc. The relaxation resting time was 3 seconds, with an acquisition time of 50 ms, contact time of 3 ms, a rotation frequency of about 4 KHz, and a resonance frequency of 75 MHz.…”

“…The most frequently studied materials are activated charcoal [6], cellulose [7], silica [8], clay [9], zeolites [10], chitosan [11], several lignocellulosic materials, agricultural waste, such as eucalyptus [12], wheat straw [12], sugarcane bagasse [13], peanut husk [14], bamboo [15], corn grains [16] among others. The cellulose stands out for being the most abundant polysaccharide in nature, and it arouses attention specially due to its low cost [1].…”

Abstract:The cellulose matrix was characterized by FTIR, 13 C NMR, XRD, TG, SEM and applied in the removal of the reactive red RB dye in an aqueous medium, with a capacity of adsorption at a pH of 2.0, and an adsorption equilibrium time which was reached at around 200 mins. The kinetic study for the system followed the Elovich model. The adsorption isotherms for the system at temperatures of 35°C, 45°C, and 55°C were adjusted to the Langmuir, Freundlich, Sips, and Redlich-Peterson non-linear models, with a capacity of adsorption for adsorbent of 5.97 mg g , respectively. The adsorption occurred by electrostatic interactions and it was favorable and spontaneous, with the influence of temperature.

“…The repeated shift due to the C-O and OH stretching suggests that both C-O and OH functional groups are involved in the binding or reacting with Pb 2+ . Figure 3 shows absorption at 3282.83 cm -1 in seeds is due to OH stretching vibration (Kumar and Tamilarasan, 2013;Zhang et al, 2013;Sivaraj et al, 2001). The band at 2918.13 and 2841.24 cm -1 is due to C-H stretching.…”

“…Figure 1 shows that the absorption at 3337.88 cm -1 in M. oleifera pods is due to OH stretching vibration (Kumar and Tamilarasan, 2013;Zhang et al, 2013;Sivaraj et al, 2001). Vibrations at 2916.32 cm -1 was due to CH stretching and 1732.08 cm -1 could be C=O (carbonyl) stretch (Lee et al, 2007).…”

This research article presents a comparative study of the adsorption properties of Moringa oleifera biomass using Pb 2+ ions as test analyte. The investigated parameters which affected the adsorption process were the effect of pH, initial concentration, adsorbent dose, contact time, and temperature. The comparison of adsorption process was evaluated in the pH range of 3 to 8, concentration range from 5 to 20 ppm, temperature varied from 25 to 80°C, variation of contact time from 15 to 80 min, and dose of the adsorbent from 0.3 to 1.2 g. The results obtained showed that a high adsorbent dose is required for high adsorption capacity. The pH of 7 was most effective with temperature set at 25°C and contact time of 60 min. The Temkin, Dubunin-Radushkevich, Langmuir and Freundlich isotherms were applied and fitted well to the data and values of the parameters of these isotherm equations were calculated. The Langmuir isotherm proved to be the overall best isotherm. The adsorbent surface functional groups were identified with Fourier Transform Infrared (FTIR) spectroscopy. The maximum adsorption capacity obtained was 98% for seed, 96% for blended, 94% for pods, and 92% for leaves. Better thermodynamic and kinetic properties were obtained with the seeds and the blended samples. In total, these results indicate that the blended moringa biosobent can be employed as a low-cost biosorbent for the removal of lead ions from water.

“…Adsorption is a physico-chemical method of treating wastewater in which activated carbon is widely used as an adsorbent for the removal of dye from colored waters due to its excellent adsorption ability, but its expense limits its usage [6]. Therefore, bio-sorbents derived from agricultural residues, such as corn stalk, fruit peel, rice husk, and sugarcane bagasse, are currently used for the removal of these dye effluents [7][8][9][10].…”

Abstract.The adsolubilisation of tetradecyltrimethyl ammonium bromide byan adsorbent termed 'organorice straw' was developed in this research to enhance the decolorization behavior of yellow20 in aqueous solutions. The organo-rice straw was characterized by elemental analysis, Brunauer-Emmett-Teller (BET) method, Fourier transform infrared spectroscopy (FTIR) technique, and scanning electron microscopy (SEM) images. Batch studies were researched to address various experimental parameters such as contact time, the initial pH solution, and initial dye concentration. Results showed that the major contents of yellow20 and organo-rice straw were carbon and hydrogen indicating their hydrophobic natures. The percentage of yellow20 that was removed bythe organo-rice straw was 96.01%, higher than the 36.44% removed by the precursor. The equilibrium adsorption was reached within 3.0 h and the amount of yellow20 adsorbed was independent of the pH0. The kinetic data were fitted to pseudo-first order, pseudosecond order, and intra-particle diffusion models. Results implied that adsorption of yellow20 by this adsorbent followed the second order kinetic model and the maximum adsorption capacity was found to be 166.55 mg.g -1 . Equilibrium isotherms were analyzed by the Langmuir, Freundlich, Temkin, and DubininRadushkevtch isotherms. The Freundlich isotherm described the isotherm data with high-correlation coefficients. The results of the study indicate that organo-rice straw is a potential and active bio-sorbent for the removal of yellow20.
