“…The analogous trend was observed in our previous work [ 30 ]. It is well known that the process of sorption from aqueous medium is accompanied by transport phenomena that under determined conditions could influence the rate of contaminant recovery [ 41 , 42 ].…”

The film binary composites polylactide (PLA)–chitosan and poly(3-hydroxybutyrate) (PHB)–chitosan have been fabricated and their functional characteristics, such as hydrolysis resistance, biodegradation in soil, and ion sorption behavior have been explored. It was established that hydrolysis temperature and acidity of solutions are differently affected by the weight loss of these two systems. Thus, in the HCl aqueous solutions, the stability of the PHB-chitosan composites is higher than the stability of the PLA-chitosan one, while the opposite situation was observed for biodegradation in soil. The sorption capacity of both composites to Fe3+ ions was investigated and it was shown that, for PHB-chitosan composites, the sorption is higher than for PLA-chitosan. It was established that kinetics of sorption obeys the pseudo-first-order equation and limiting values of sorption correspond to Henry’s Law formalism. By scanning electron microscopy (SEM), the comparative investigation of initial films and films containing sorbed ions was made and the change of films surface after Fe3+ sorption is demonstrated. The findings presented could open a new horizon in the implementation of novel functional biodegradable composites.

“…This suggests that the sorption process is predominantly driven by chemical adsorption [55], involving electron sharing and the formation of chemical bonds [56]. Typically, the adsorption of adsorbates from solution to adsorbents involves three stages: (I) boundary layer diffusion, which transports the adsorbates from the solution onto the surface of adsorbents; (II) intra-particle diffusion, which transfers adsorbates from the surface to the interior particles of adsorbents; and (III) adsorption equilibrium, which repairs the adsorption reaction occurring on the active sites distributed within the interior particles of the adsorbents [45,55,57]. It is worth noting that the adsorption equilibrium usually affects little on the overall adsorption rate.…”

Biochar adsorption has emerged as a favorable and environmentally friendly approach for removing metals such as chromium (Cr) from wastewater. However, the use of pristine biochar (PBC) is limited due to its finite adsorptive capacity, selectivity, and potential for secondary pollution. In this study, a novel bifunctionalized magnetic biochar (BMBC) was fabricated by incorporating cystamine as a ligand and glutaraldehyde as a crosslinker into alkali-treated magnetic biochar (MBC). This chemical modification introduced numerous amino groups and disulfide bonds onto the surfaces of BMBC. The biochar adsorbents’ surface morphologies, crystal structures, and texture properties were characterized using SEM, XRD, and N2 adsorption-desorption techniques. The specific surface area was determined using the BET method. Furthermore, the surface functional groups and elemental compositions before and after adsorption were analyzed using FTIR and XPS, respectively. The results demonstrated higher Cr(VI) removal efficacy of BMBC (100%) than MBC (72.37%) and PBC (61.42%). Optimal conditions for Cr(VI) removal were observed at a solution pH of 2, a temperature of 50 °C, a reaction time of around 1440 min, and an initial adsorbate concentration of 300 mg/L. The sorption process followed a chemical mechanism and was controlled by monolayer adsorption, with a maximum adsorption capacity of 66.10 mg/g at 50 °C and a pH of 2, as indicated by the larger fitting values of the pseudo–second-order and Langmuir models. The positive ∆Ho and ∆So values and negative ∆G0 values suggested a spontaneous and endothermic Cr(VI) adsorption process with high randomness at the solid/liquid interface. The removal of Cr(VI) was attributed to the reduction of Cr(VI) into Cr(III) facilitated by the introduced amino acids, sulfur, and Fe(II), electrostatic interaction between Cr(VI) in the solution and positive charges on the adsorbent surface, and complexation with functional groups. The presence of co-existing cations such as Cu(II), Cd(II), Mn(II), and K(I) had little effect on Cr(VI) removal efficiency. At the same time, the co-existence of anions of Cl−, NO3−, SO42−, and HPO42− resulted in a 7.58% decrease in the Cr(VI) removal rate. After five consecutive adsorption/desorption cycles, BMBC maintained a high Cr(VI) removal rate of 61.12%. Overall, this novel BMBC derived from rice straw shows great promise as a biosorbent for treating Cr(VI) in wastewater.

“…However, biological method is not efficient in removing fused aromatic ring antibiotics, such as CIP [9]. Meanwhile, the absorption method [10] is only to absorb and transfer pollution to other forms of pollution in absorbent solid waste. While, the application of Advanced Oxidation Processes (AOPs) with ozone microbubbles [11], UV light [12], or catalysts, has been reported as a promising method for the oxidative removal of various organic contaminants in polluted water [13].…”

Degradation of Ciprofloxacin (CIP) Antibiotic Waste using The Advanced Oxidation Process (AOP) Method with Ferrate (VI) from Extreme Base Electrosynthesis

2023

View full text Add to dashboard Cite

Ciprofloxacin (CIP) antibiotic liquid waste is the most common waste found in hospital discharge waters. The accumulation of CIP can increase mutation, microbial resistance, and toxicity in the environment due to its low biodegradability and longevity in waters. Thus, methods for eliminating CIP are important. The Advanced Oxidation Process (AOP) method with ferrate (VI) has good redox potential in water disinfection, and degradation of organic and inorganic pollutants. Therefore, this study aims to degrade CIP waste with ferrate (VI). The ferrate (VI) used was synthesized from the electrolysis of transformer scrap metal plates under extremely alkaline conditions. The success of the synthesis was proven by the presence of FeO(OH) groups characterized using FTIR, XRF, and XRD. Then, the effect of time, pH, and CIP degradation was studied. The results showed that the maximum performance was obtained at pH 7 and 120 min with the addition of 1.1 mg ferrate at initial CIP concentration of 30 mg/L. The concentration of CIP decreased with increasing treatment time which was confirmed by UV-Vis Spectrophotometer. This condition is able to degrade 86.7 % of CIP. In addition, the LC-MS results show that degradation occurs due to a reaction between HFeO4-/H2FeO4 and the active site of piperazine ring antibiotics. This shows that Ferrate has a promising potential to reduce ciprofloxacin antibiotic pollution from hospital wastewater for a better environment.
