“…Based on the correlation factor (R 2 ¼ 0.9999), the adsorption process of the RBBR onto XI followed the Pseudo-second order kinetic model. This result fits with the result obtained when Rhodamine B removed by X. strumarium L. seed hull [25]. The equilibrium constant value from the Pseudo-second order reaction was 0.46 mg g À1 .…”

“…In this type of isotherm, the adsorbent surface is heterogonous, the adsorption can be reversible and can occur in a multilayer. Freundlich's isotherm was used in the removal of RBBR by durian seed activated carbon [52] and in Rhodamine B dye removal by Xanthium strumarium L. seed hull [25].…”

In this study, the adsorption capacity of toxic and recalcitrant organic pollutant(s) Remazol Brilliant Blue R (RBBR) onto the invader Xanthium İtalicum (XI) plant was assessed using the Response Surface Method (RSM). The adsorp-tion behavior of RBBR was determined by the spectrophotometric method, FTIR and SEM analysis were used to characterize XI, Brunauer, the Emmett and Teller (BET) analysis was accomplished to find the surface area of the ad-sorbent. The experiment procedures were planned by the Central Composite Design (CCD) whereby a model was built to examine the effects of the different parameters and the possible interaction between them. The correlation factor (R2) for the developed model was 0.985, suggesting that the model could achieve 98.5% of RBBR removal through an adsorption process. The desirability of 0.992 can be attained using the identified optimum conditions: XI = 3g, pH = 9, Time = 84min, RBBR = 50ppm. Under these conditions, the adsorption capacity reached 1.59 mg.g-1, and the removal percentage reached 95%. Freundlich isotherm had the best-fitted values with R2 of 0.999. Furthermore, the adsorption of RBBR onto XI was found to be pseudo-second-order kinetic with R2=0.999. Also, the recovery of RBBR from XI was studied through desorption experiments in presents of 0.5M NaOH. The recovery percentage after 120 min reached 47%. The maximum recovery percentage reached 73% at 24h.

“…The process of adsorption is more favorable than the chemical methods, it is simpler and more flexible (Tobías et al 2018). In addition to that, the adsorption process does not generate any sludge as in the biological process (Khamparia and Jaspal 2017). For these reasons, the adsorption process became the most frequent process.Activated carbon had been used widely as an adsorbent.…”

Invasive plants reduce the yield by inhibiting the development of agricultural products. In this study, invasive (CS) plant which is agricultural waste was used as adsorbent for removal of Malachite Green (MG) from aqueous solution. The adsorbent-adsorbate relationship was examined by the spectrophotometric method and Fourier transform infrared (FTIR). The surface morphology was determined by scanning electron microscope (SEM). CS surface area was measured by Brunauer, the Emmett and Teller (BET) analysis. The experiments were designed and modeled by RSM. The correlation factor of the developed model was 0.984. The capacity of 90.816 mg.g-1 was achieved when MG solution with concentration of 312.5 mg.L-1 was adsorbed onto 0.325 g CS for 75 min at a pH of 7.5. In this work the shaking velocity and the adsorbent size were 150 rpm and 30 mesh respectively. Langmuir, Freundlich, Temkin, and Dubinin-Radushkevich (D-R) isotherms were studied. Temkin isotherm had the highest R 2 of 0.997. The kinetics models of the adsorption process were investigated and fitted with pseudo-second-order kinetic (R 2 = 0.9982). The intraparticle diffusion model reflected the involved two steps; the first comprehended the boundary diffusion layer, while the second introduced the intraparticle diffusion effects. The adsorption was found to be endothermic with a Gibbs free energy of-4.47 KJ.mol-1. It was noted that the adsorption process was irreversible with a max percentage of desorption process of 2.16%. Column experiments were conducted to realize the adsorption process. The efficiency of the column reached 99.5% after 40 min and stilled constant. As a result, CS has shown a potential for MG removal from aqueous solution.

In this study, basalt is used as a catalyst for the removal of the dyes malachite green (MG) and crystal violet (CV) from aqueous solution. First, the effect of sintering temperature on Fenton process is optimized using basalt powder. Different analysis techniques such as X-ray diffraction (XRD), X-ray fluorescence (XRF), Brunauer-Emmett-Teller (BET), and Fourier-Transform Infrared Spectroscopy (FTIR) are used to characterize basalt powder. It is concluded that Fe 2 O 3 in basalt powder is the main component responsible for the degradation of dyes in the Fenton process. The maximum degradation of the dyes (97.02% for CV and 95.71% for MG) is obtained at 10 mg L −1 dye concentration, solution pH of 6, 1 g L −1 catalyst amount, and 12 mm H 2 O 2 concentration for 2 h. The results are fitted to the second-order kinetic model. The reusability of the catalyst is explored, and the basalt showed stability in the removal efficiency for repeated five cycles. The degradation of real textile wastewater is also studied. The removal efficiency reached up to 60.33% at optimum conditions of pH 2, basalt amount of 5 g L −1 , H 2 O 2 concentration of 400 mm. The results showed that the basalt powder is successfully utilized as a heterogeneous catalyst for textile wastewater treatment.
