“…As the amount of adsorbent increased, the number of available adsorption sites increased, which directly increased the rate of adsorption. 13,14 It can be deduced from Figs. 8 and 9, that the value of q e /logq e increased linearly with c t or logc t .…”

This study investigated the utilisation of Luffa cylindrica activated carbon as a low-cost adsorbent in the removal of vanadium(V) from textile industry effluent in a batch adsorption experiment. The adsorption rate was studied for contact time, pH, and adsorbent dosage. The effect of pH on vanadium(V) removal was studied with 0.2 g/100 ml adsorbent dose, 10 min contact time, and textile effluent solution. The maximum removal efficiency was 99.90 % at pH 4, 97.43 % at 60 min of contact time, and 97.83 % at an adsorbent dosage of 1.0 g. The characterisation results from FTIR and SEM indicated that the adsorbents’ potential was fully exploited. In this study, the experimental findings were fitted using Langmuir and Freundlich isotherm models. Freundlich model gave a better fit of the experimental data. The kinetic data by the pseudo-second order kinetic model gave a better fit than the pseudo-first order kinetic model.

“…The main metals that caused adverse health effects are chromium and lead. The characterization of the wastewater is applied to evaluate the effectiveness of the LAC in removing Cr (VI) present (Bayuo, Pelig‐Ba, & Abukari, 2019; Eletta et al., 2018; Yusuff, 2018).…”

“…These shortcomings have made researchers seek alternative techniques for heavy metal remediation. Adsorption using naturally available materials has been reported to be efficient in the removal of hazardous metals from industrial effluents (Eletta, Mustapha, Ajayi, & Ahmed, 2018; Hoan et al, 2020; Ullah et al., 2020). The materials employed in this technique often range from the use of microbes and naturally abundant plant materials to dead waste biomass (Gavrilescu, 2004; Malik et al., 2006).…”

Luffa cylindrica was applied as a low-cost adsorbent for removing chromium (VI) from textile industry effluent in this study. The adsorbent was characterized using scanning electron micrograph (SEM). A batch mode experiment was conducted to study the effect of pH, contact time, and adsorbent dosage on the adsorptive potential of the prepared luffa cylindrica activated carbon. The characterization results from SEM indicate that the adsorbents' potential was fully exploited in this study. A significance test conducted using ANOVA indicated that contact time and adsorbent dosage had the most effect on the adsorptive removal of Cr (VI). The optimum removal efficiency was 99.90% at pH 8.0, 99.8% at 60 min of contact time, and 99.82% at an adsorbent dosage of 1.0 g. The experimental results were analyzed using the Langmuir and Freundlich adsorption isotherm models, and the Freundlich isotherm provided a better correlation for Cr (VI) adsorption. The kinetic data by the pseudo-first-order kinetic model gave a better fit than the pseudo-second-order kinetic model.

“…A variety of biological, chemical and catalytic methods are used to remove dyes from wastewater [10][11][12][13]. Among them, the adsorption of dyes on solids with a high specific surface area is widely used due to its high efficiency, reliability, low cost, versatility and ease of operation [14][15][16].…”

Several important synthesis pathways for metal-organic frameworks (MOFs) were applied to determine how the synthesis methods and conditions affect the structure and adsorption capacity of the resulting samples. In the present work, three different synthesis routes were used to obtain copper trimesinate coordination polymer: Slow evaporation (A), solvothermal synthesis using a polyethylene glycol (PEG-1500) modulator (B), and green synthesis in water (C). This MOF was characterized by elemental analysis, infrared spectrometry, X-ray diffraction, scanning electron microscopy, thermogravimetry and volumetric nitrogen adsorption/desorption. The samples have permanent porosity and a microporous structure with a large surface area corresponding to the adsorption type I. The obtained MOF was tested as a sorbent to remove organic dyes methylene blue (МВ), Congo red (CR) and methyl violet (MV) as examples. Dye adsorption followed pseudo-first-order kinetics. The equilibrium data were fitted to the Langmuir and Freundlich isotherm models, and the isotherm constants were determined. Thermodynamic parameters, such as changes in the free energy of adsorption (∆G0), enthalpy (∆H0), and entropy (∆S0), were calculated. Thermolysis of copper trimesinate leads to the formation of carbon materials Cu@C with a high purity.
