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.

Complexing properties of the chelating ion exchanger based on spherical cellulose modified by the functional groups of diethylenetriaminetetraacetic acid, Ostsorb DTTA, have been studied in the sorption of lead from aqueous medium at various experimental conditions, such as pH, the dynamic or static arrangement of experiment, the presence of other compounds, the concentration of the ion being sorbed, the form of ion exchanger etc. The results have been compared with the data found with the known selective ion exchanger Dowex A-1. Ostsorb DTTA exhibits good kinetics of the ion exchange at the exchange capacity of 210 mg Pb g-1 for pH 6. For some applications, its lower mechanical stability and high water content in the swollen particles may be unfavourable.

A model of moisture absorption by basalt-plastic reinforcement was developed and experimentally confirmed, taking into account Fickian diffusion, structural relaxation and design features of reinforcement at the initial stage of climatic aging. The analytical solution can be used to approximate the kinetics of moisture sorption of other reinforced polymer composites. Keywords: reinforced polymer composite, basalt-plastic reinforcement, climatic aging, moisture sorption, abnormal diffusion, relaxation model, time dependence of the diffusion coefficient.

Kinetics Of

The adsorption behavior of methyl orange aqueous solution was investigated on husk-based activated carbon. The effects of key factors, i.e., degassing pretreatment, adsorption time, temperature, adsorbent dosage and initial concentration, on the adsorption efficiency were measured. The kinetic adsorption curves and adsorption isotherms were fitted with theoretical model. The results show that the removal efficiency of methyl orange could be significantly improved by degassing pretreatment, prolonging the time, lowering temperature or reducing the initial concentration. In the context, adsorption equilibrium will be achieved up 90min. Furthermore, adsorption rate will be enhanced by the increase of the amount of activated carbon. In conclusion, adsorption isotherm and adsorption kinetics can be fitted well with Freundlich equation and pseudo-first Lagergren model, respectively.
