“…According to their hydrophilic properties, surfactants are categorized into four classes (cationic, anionic, amphoteric, and non-ionic) [5,6]. Ionic surfactants (anionic and cationic surfactants) constitute approximately two-thirds of all surfactants, and anionics constitute more than 90% of all Ionics [7].…”

“…The removal efficiency of surfactants from aqueous environments depends on the method of treatment employed [18]. Various procedures are employed for removing or destroying surfactants, including an anaerobic fluidized bed reactor (FBR) [19], chemical or electro-chemical oxidation, membrane technology, chemical precipitation, and photo catalytic degradation [6,17,[20][21][22]. However, the limitations of biological procedures and difficulties in using other technologies (such as membranes) or adsorbing procedures challenge us to develop and employ new methodologies to deal with this issue [5].…”

The aim of our study was to investigate the effectiveness of Fenton and photo-Fenton processes for removing anionic surfactants from aqueous solutions. The study was conducted using 200 mgL and 120 mgL -1 ferrous ion) were 69.38 and 86.66%, respectively, which is consistent with the significant increase in the rate of LAS removal efficiency with reaction time (P<0.05). In conclusion, anionic surfactants removal was significantly correlated with reaction time by both methods, but showed less dependence on H 2 O 2 and Fe 2+ concentrations.

“…The pH value of As(V) solution is an extreme important factor to influence the adsorption process, because it determines the anionic species of arsenic along with the surface changes and the ionization of adsorbents [54,55]. The effect of pH on the adsorption capacity was investigated in the pH range of 4.0-10.0, in which 40.0 mg BUC-17 were added to 200 mL As(V) solution with initial concentration of 10 mg L −1 under 298 K. As shown in Fig.…”

Arsenic contamination is a great threat worldwide due to its toxicity and hardly degradable. The development of highly efficient adsorbents is an essential challenge in the water treatment field. A 2D metal-organic framework [Co 3 (tib) 2 (H 2 O) 12 ] (SO 4) 3 (BUC-17) has been synthesized by hydrothermal method, and was utilized as an efficient adsorbent to remove As(V) from contaminated water. The results showed that BUC-17 have higher adsorption capacity toward As(V) than most counterpart adsorbents, its maximum uptake capacity reached 129.2 mg g −1 at 298 K. The adsorption kinetics and isotherm behaviors were well fitted with pseudo-second-order and Langmuir model, respectively. The thermodynamic parameters such as free energy change ΔG°, enthalpy change ΔH° and entropy change ΔS° were both negative during the sorption process, suggesting that the adsorption process of BUC-17 towards As(V) was spontaneous and exothermal. The influence of pH and foreign ions on the adsorptive removal of As(V) using BUC-17 were investigated. The results showed that pH values have significant influence while co-existed anions (unless phosphate) exert slight effect on adsorption capacity. Finally, a corresponding adsorption mechanism was proposed and confirmed by scanning electron microscopy, Fourier Transform infrared spectra (FTIR) and X-ray photoelectron spectroscopy analysis.

The optimization of ultrasonication process applied to linear alkyl benzene sulfonic acid (LABSA) degradation is investigated with response surface methodology in this study. Methylene blue active substance assay is used as a mean to monitor the degradation of LABSA. The effects of independent process variables (initial LABSA concentration, pH, and reaction time) on main material degradation are investigated. Among the independent variables, the greatest effect on LABSA degradation is observed for reaction time. Besides this, the effects of both reaction time and initial LABSA concentration are quite similar. The initial pH value of the solution has a lower effect on degradation performance when compared to other parameters. The predicted maximum detergent degradation was 75% at the optimal conditions of pH 7.8, initial LABSA concentration of 20 mg L−1, and reaction time of 70 min. Specific cost of LABSA degradation by ultrasonic treatment varies from 0.579 to 4.657 Euro g−1 removal LABSA. According to the results of sonication treatment applied to real wastewater, approximately 40% of the LABSA degradation is achieved at three pH values (5.27, 7.50, and 9.59). Because the original pH of the real wastewater is 9.59, it is more feasible to run experiments at this pH value.
