“…The adsorption behaviors of atrazine with/without BPA onto WAC, WSAC, and ASAC were similar. The adsorption rates of atrazine with/without BPA onto WAC, WSAC, and ASAC were the fastest at first 1 h, after that the rates slowed down, which was because the concentration of atrazine and the active sites of the adsorbent sample reduced as the reaction going on [22]. The adsorption progress reached the equilibrium during 5 h (Figure 2).…”

“…The experimental data were fitted with Langmuir (Equation (6)), Freundlich (Equation (7)), Temkin (Equation (8)), and Dubinin–Radushkevich (D–R) (Equation (9)) isotherm models [22]. The residual root-mean squared error (RMSE) [19] function values can be analyzed using the Equation (10): q e = q m K L C e /(1 + K L C e ), q e = K F C e 1/ n , q e = B ln ( ACe ), Lnq e = lnq m − K d ln ( 1 + 1 / Ce ), RMSE = [∑( q e exp n − q e cal n ) 2 /(n − 1)] 1/2 , R L = 1/(1 + C m K L ) , where q m (mg/g) is the maximum adsorption capacity; q e (mg/g) is the adsorption amount of the adsorbate onto the adsorbents at the equilibrium time; K L (L/mg) and K F (L/mg) are the Langmuir and Freundlich constants, respectively; n is the empirical parameter; b (J/mol), A (L/mg), R (8.314 J/(mol∙K)), and T (K) are the Temkin constants related to the thermal constant of adsorption, equilibrium binding constant, gas constant, and absolute temperature, respectively; K d = R 2 T 2 / E 2 ; E (J/mol) is the constant related to free energy; and R L is the dimensionless separation factor.…”

Activated carbons (ACs) based on apricot shells (AS), wood (W), and walnut shells (WS) were applied to adsorb atrazine in co-solutions. To study the effect of Bisphenol A (BPA) on the adsorption behavior of atrazine, the adsorption performance of ACs for BPA in single solution was studied. The results demonstrated that the adsorption kinetics of BPA fitted the pseudo-second-order model, the adsorption isotherms of BPA followed the Langmuir model. Meanwhile, the adsorption kinetics of atrazine fitted the pseudo-second-order kinetics model and the isotherm was consistent with the Freundlich model both in single solution and co-solution. In addition, competitive adsorption was observed when atrazine coexisted with BPA or humic acid. For the adsorption capacity, the adsorption amount of ASAC, WAC, and WSAC for atrazine obviously decreased by 18.0%, 30.0%, and 30.3% in the presence of BPA, respectively, which was due to the π−π interactions, hydrophobic interactions, and H-bonds, resulting in the competitive adsorption between atrazine and BPA. This study contributes to the further understanding of the adsorption behavior for atrazine in co-solution.

“…Adsorption and activated carbon based technologies have also been widely used for several environmental applications [19][20][21][22][23][24]. To that end, the conversion of agricultural wastes into granular activated carbon (GAC) and its use for pollution control applications, has also attracted much attention, considering its multi-faceted and inherent economical, and environmental advantages.…”

The present work investigated the application of granular activated carbon (GAC) derived from date palm pits (DPP) agricultural waste for treating gaseous ammonia. Respective findings indicate increased breakthrough time (run time at which 5% of influent ammonia is exiting with the effluent gas) with a decrease in influent ammonia and increase in GAC bed depth. At a gas flow rate of 1.1 L/min and GAC column length of 8 cm, the following breakthrough trend was noted: 1295 min (2.5 ppmv) > 712 min (5 ppmv) > 532 min (7.5 ppmv). A qualitatively similar trend was also noted for the exhaustion time results (run time at which 95% of influent ammonia is exiting with the effluent gas). The Fourier Transform Infrared Spectroscopy (FTIR) findings for the produced GAC indicated some salient functional groups at the produced GAC surface including O–H, C–H, C–O, and S=O groups. Ammonia adsorption was suggested to result from its interaction with the respective surface functional groups via different mechanisms. Comparison with a commercial GAC showed the date palm pits based GAC to be having slightly higher breakthrough and exhaustion capacity.

“…However, after carbonisation, this content may increase above 80% or even 95% for ACs, which is interesting since it can lead to an elevated and developed porosity [ 37 ]. The high cellulose content also plays a crucial role in developing mesopore structure in ACs while lignin, for example, can promote the formation of layered structure and maximisation of micropores during the preparation of AC [ 38 ].…”

: Some recent developments in the preparation of biomass carbon electrodes (CEs) using various biomass residues for application in energy storage devices, such as batteries and supercapacitors, are presented in this work. The application of biomass residues as the primary precursor for the production of CEs has been increasing over the last years due to it being a renewable source with comparably low processing cost, providing prerequisites for a process that is economically and technically sustainable. Electrochemical energy storage technology is key to the sustainable development of autonomous and wearable electronic devices. This article highlights the application of various types of biomass in the production of CEs by using different types of pyrolysis and experimental conditions and denotes some possible effects on their final characteristics. An overview is provided on the use of different biomass types for the synthesis of CEs with efficient electrochemical properties for batteries and supercapacitors. This review showed that, from different biomass residues, it is possible to obtain CEs with different electrochemical properties and that they can be successfully applied in high-performance batteries and supercapacitors. As the research and development of producing CEs still faces a gap by linking the type and composition of biomass residues with the carbon electrodes’ electrochemical performances in supercapacitor and battery applications, this work tries to diminish this gap. Physical and chemical characteristics of the CEs, such as porosity, chemical composition, and surface functionalities, are reflected in the electrochemical performances. It is expected that this review not only provides the reader with a good overview of using various biomass residues in the energy storage applications, but also highlights some goals and challenges remaining in the future research and development of this topic.
