“…The peaks at 1625 cm − 1 and 1387 cm − 1 were attributed to the characteristic absorptions of amide I and III bands related to ν(C = O) and ν(C − N) based on cyclized H 2 ibga in Zn-CP [34]. Two new weak intensity absorption peaks appeared at about 686 cm − 1 and 451 cm − 1 in the spectrum of Zn-CP due to the existences of Zn − O and Zn − N bonds [35].…”

A new 2D homochiral zinc coordination polymer (Zn-CP) with 52-member rings was synthesized by solvothermal method. X-ray single crystal diffraction results show that the initial ligand (H2ibga = (4-(1H-imidazol-1-yl)benzyl)-L-glutamic acid) cyclized and crystallized in monoclinic with space group P2 after coordination with zinc(II) ions. Phase purity and thermal stability of Zn-CP were verified by X-ray powder diffraction (PXRD) and thermogravimetric (TG), respectively. Additionally, Zn-CP can recognize tetracycline (TC), Fe3+ and ascorbic acid (AA) rapidly and selectively in aqueous solution, with low detection limits (LODs) of 3.49 nM, 4.42 nM and 0.38 µM, respectively. The detection mechanisms have been investigated in detail.

“…The adsorption capacities of several representative materials in phenol solutions are presented in Table 4. The results illustrated that NTPOP and MCPOP have a higher adsorption capacity in solution compared to the reported adsorbent materials [42][43][44][45][46][47]. The adsorption capacity of activated carbon for TCP is 16.23 mg/g.…”

Phenolic pollutants released from industrial activities seriously damage natural freshwater resources, and their elimination or reduction to safe levels is an urgent challenge. In this study, three catechol-based porous organic polymers, CCPOP, NTPOP, and MCPOP, were prepared using sustainable lignin biomass-derived monomers for the adsorption of phenolic contaminants in water. CCPOP, NTPOP, and MCPOP showed good adsorption performance for 2,4,6-trichlorophenol (TCP) with theoretical maximum adsorption capacities of 808.06 mg/g, 1195.30 mg/g, and 1076.85 mg/g, respectively. In addition, MCPOP maintained a stable adsorption performance after eight consecutive cycles. These results indicate that MCPOP is a potential material for the effective treatment of phenol pollutants in wastewater.

“…The desorption efficiency at basic conditions indicates that an electrostatic interaction exists between the dye molecules and the aqueous solution. The high concentration of H + ions in 0.1 M HCl (pH 1~2) destructed the adsorbent structure, resulting in functional group collapse [29]. Therefore, 0.1 M NaOH (pH 11~12) increased the alkalinity of the aqueous solution, separating the adsorbed MB dye molecule that had been adsorbed on the adsorbent, resulting in a high percentage of dye removal.…”

A Potential Approach for Converting Rubber Waste into a Low-Cost Polymeric Adsorbent for Removing Methylene Blue from Aqueous Solutions

Exploiting waste materials to make cost-effective adsorbents and waste management methods are gaining more attention. In the current study, rubber wastes derived from dipping tank coagulum (DTC) in the glove manufacturing industry were converted into a novel polymeric-adsorbent via a simple sulfonation reaction with concentrated sulphuric acid and was used for the adsorption of methylene blue (MB) dye from aqueous solutions commonly found in contaminated waters. FT-IR, EDX, FESEM, and BET techniques were used to characterize the rubber waste before and after modification. The highest MB removal efficiency of 99.03% was achieved in the condition of initial concentration, adsorbent dosage, pH, contact time, and temperature were 15 mg/L, 30 mg, pH 7, 300 min, and 25 °C, respectively. The adsorption of MB was analyzed using experimental data fitted in a monolayer isotherms model with a maximum adsorption capacity of 119 mg/g. The kinetic model was revealed to agree with the pseudo-second-order kinetic model. Furthermore, SRW retained 90.45% of the removal percentage after four cycles of the repeated adsorption-desorption process. Conclusively, these findings suggest that rubber waste could be a suitable low-cost adsorbent to remove organic dyes from polluted water.
