“…The similar result has also been reported in previous studies for Methylene Blue adsorption (Foo and Hameed, 2012;Nasrullah et al, 2019), and in the NH3 adsorption on corncob activated carbon (Gebreegziabher et al, 2019). Langmuir isotherms indicates the monolayer adsorption where there is no interaction in adsorbate molecules (El maguana et al, 2020), and the carbon surfaces have homogeneous structures and identical active sites (Kutluay et al, 2019). Moreover, the equilibrium parameter (RL) value is in the range of 0<RL<1, suggesting that the NH3 adsorption using MP-AC is favorable (Hamzaoui et al, 2018).…”

Mangosteen peel can be used as an activated carbon precursor because of its high lignin content and hardness. In this study, mangosteen peel activated carbon (MP-AC) was prepared by a physical activation method using CO2 at 850°C. The Brunauer-Emmett-Teller (BET) analysis was used to assess the optimal activation time to identify the largest surface area. The properties of MP-AC were characterized by the SEM-EDS and FTIR analyses. The results showed that MP-AC obtained from the 120-minute activation time had the largest BET specific surface area of 588.41 m2/g and was selected as an adsorbent in the dynamic adsorption of ammonia gas. The values of moisture content, ash content, and iodine number of MP-AC were 6.07%, 9.8%, and 1153.69 mg/g, respectively. Breakthrough curve indicated that with lower inlet concentration and higher adsorbent mass, longer breakthrough time is reached. Equilibrium data was best fitted to the Langmuir isotherm, while the pseudo-first order kinetic model favorably described the adsorption kinetics. The results revealed a potential to utilize MP-AC as an adsorbent for ammonia gas removal with average NH3 adsorption capacity of 0.41 mg/g.

“…e amount of methyl orange removed by adsorption onto the activated carbon at the equilibrium time was 194 mg/g. Adsorption kinetics models provide invaluable information on the controlling mechanisms of adsorption process [34]. e overall adsorption process may be controlled by either external or film diffusion, pore diffusion and adsorption on the pore surface, or a combination of more than one step [34].…”

Batch adsorption experiments have been conducted to investigate the removal of methyl orange from aqueous solution by an activated carbon prepared from prickly pear seed cake by phosphoric acid activation. The adsorption process has been described by using kinetic and isotherm models. The kinetic of adsorption was examined by pseudo-first-order, pseudo-second-order, and intraparticle diffusion models. Adsorption isotherm was modeled using Langmuir, Freundlich, Temkin and Dubinin–Radushkevich isotherms. The adsorption process of methyl orange was well explained by the pseudo-second-order model and Freundlich isotherm. Also, pseudo-n-order model has been applied to estimate the order of adsorption kinetic and it was found equal to 2 which confirm the good accuracy of the pseudo-second order. Moreover, Dubinin–Radushkevich isotherm reveals that the adsorption of methyl orange onto activated carbon was a physisorption process in nature. The adsorption capacity of activated carbon was found to be 336.12 mg/g at temperature 20°C and pH∼7. These results demonstrated that the prickly pear seed cake is a suitable precursor for the preparation of appropriate activated carbon for dyes removal from aqueous solution.

“…This type of slight desorption was due to the increased randomness and greater solubility of dye ions at a higher temperature and indicated exothermic adsorption. 69 However, for AC, dye uptake was found to increase from 5.2 to 10.9 × 10 −4 g with an increase in temperature from 27 to 50°C. Increased penetration of adsorbate molecules into the adsorbent micro-pores at higher temperature was mainly responsible for an increase in the dye uptake in the case of AC, indicating endothermic adsorption.…”

In the quest to find an eco-friendly, cost-effective and efficient alternative to expensive and non-biodegradable activated charcoal (AC), in the current study the potential of a weed, parthenium hysterophorus (PH), has been explored as a bioadsorbent for purification of textile wastewater. Root, stem and leaves of PH weed have been used as bio-adsorbents in raw and surface-treated forms and compared with AC for removal of toxic textile dye CI Reactive Red 239 (Remazol Brilliant Red 3BS [RBR 3BS]) from wastewater. The surface treatment carried out using QAS (N-Cetyl-N,N,N-trimethylammonium bromide) in the current study is a novel way to enhance the dye adsorption capacity of raw adsorbents of PH. Characterisation tools like Fourier Transform-infrared spectroscopy, scanning electron microscopy, elemental analysis and potential of zero charge have been used to confirm the surface treatment. The impact of various process variables like pH, dosage of adsorbent, contact time, solution temperature and dye concentration have been studied. Isothermal, kinetic and thermodynamics modelling for adsorption data have been thoroughly investigated to ascertain the mechanism of adsorption. Statistical error functions like root mean square error, chi-square test, sum of absolute error and normalized standard deviation (NSD) have been used to validate the adsorption data. Results revealed that novel surface treatment significantly improved the dye adsorption capacity of raw PH adsorbents (ca. 15-16 times). Of all the weed bio-adsorbents, surface-treated PH stem showed the highest dye adsorption capacity (105 mg/g), which was 10folds greater than commercial grade AC (10.4 mg/g at 27°C). For both adsorbents, surface-treated PH stem and AC, adsorption followed pseudo-second order kinetics, and the Langmuir isotherm was the best fit with film diffusion as a rate-controlling step. Thermodynamic parameters infer the spontaneous and exothermic nature of adsorption. Therefore, in the current study, surface-treated PH stem bio-adsorbent has been revealed as a superior alternative to AC for the removal of RBR 3BS dye from wastewater, opening a new gateway to the utilisation of waste weeds for the purpose of wastewater treatment.How to cite this article: Bapat S, Jaspal D, Malviya A.
