“…Up to now various adsorbents have been prepared for phenol removal from aqueous media, most of which can be grouped as activated carbons [33,36], polymeric adsorbents [20,21,37], and low-cost adsorbents [6,38,40] (including inorganic adsorbents [6]). The typical adsorbents and their properties are presented in Table 5.…”

“…A vast number of materials have also been examined as potential adsorbents for phenol removal in wastewater treatment. The eminent among them includes silica gel (Førland and Blokhus 2007;An et al 2009), red mud (Wang et al 2008;Tor et al 2006), zeolites (Damjanović et al 2010;Yousef and El-Eswed 2009;Melidis 2015), activated alumina (Danis et al 1998;Adak and Pal 2006) and activated carbon. But because of the expensive nature of the above materials, there is a need to do further research to produce adsorbents from locally available agricultural materials (Hartmann et al 2014;Banat and Al-Asheh 2000).…”

In this paper, the feasibility of the dry stem of Lantana camara waste as an adsorbent to remove phenol from aqueous solution was investigated in a packed-bed column. The effect of bed height (5, 10, 15 cm), initial phenol concentration (100, 150, 250 mg L ) on the adsorption were studied by evaluating the breakthrough curves. The following models were used to assess the column performance: Thomas, Adams-Bohart, Yoon Nelson, Modified dose-response, linear driving force model based on fluid phase concentration difference (LDFC) and linear driving force model based on particle phase concentration difference (LDFQ). The Thomas model and the LDFC model were in good agreement with the experimental data. The bed depth service time (BDST) model was used to predict adsorption performance at other experimental conditions. The maximum adsorption capacity was found to be 149.77 mg g −1 , confirming that Lantana camara is a suitable adsorbent for the removal of phenol from aqueous solution.

The present work investigates the potential of Lantana camara, a forest waste, as an adsorbent for the phenol reduction in wastewater. Batch studies were conducted with adsorbent treated with HCl and KOH to determine the influence of various experimental parameters such as pH, contact time, adsorbent dosage, and phenol concentration. The experimental conditions were optimized for the removal of phenol from wastewater. Equilibrium isotherms for the adsorption of phenol were analyzed by Freundlich, Langmuir, Temkin, and Dubinin-Radushkevich isotherm models. Thermodynamic parameters like the Gibbs free energy (ΔG°), enthalpy (ΔH°), and entropy (ΔS°) were also determined and they showed that the adsorption process was feasible, spontaneous, and exothermic in the temperature range of 298–328 K. The kinetic data were fitted with pseudo-second-order model. The equilibrium data that followed Langmuir model with the monolayer adsorption capacity was found to be 112.5 mg/g and 91.07 mg/g for adsorbent treated with HCl and KOH, respectively, for the concentration of phenol ranging from 25 to 250 mg/L. This indicates that the Lantana camara was a promising adsorbent for the removal of phenol from aqueous solutions.
