Summary: In this study, waste hazelnut shell was effectively modified to remove tetracycline and cephalexin from water and reduce their residual antimicrobial activity. Response surface methodology was employed to determine the optimal conditions for removal efficiency. The RSM design predicted removal efficiencies of 37.34% and 83.07% for tetracycline and cephalexin, respectively. Various isotherm models were applied to the equilibrium data, and acute tests were conducted to evaluate the toxicity after biosorption. The biosorbent exhibited significant biosorption capacity and reduced toxicity for tetracycline and cephalexin.

Summary: This study investigates the effectiveness of organoclay, derived from the modification of raw clay with Cetyltrimethylammonium Bromide (CTAB) surfactant, as an adsorbent to remove anionic dye methyl orange (MO) from synthetic aqueous solutions. Physicochemical properties of raw clay and modified clay are characterized using FTIR, XRD, and SEM-EDX. Response surface methodology (RSM) based on Box Benhken design is employed to evaluate the interaction between three independent variables (pollutant concentration, adsorbent mass, and dye solution pH). Results show that the removal efficiency of MO is dependent on pH and dose of the composite, with maximum adsorption (99%) achieved under optimal conditions of 0.5 g adsorbent dose, 60 min reaction time, and pH 6. The Langmuir isotherm model accurately describes the adsorption process, with a maximum uptake of 15.58 mg/g. The adsorption kinetics follow the pseudo-second order model. The composite can be reused for 5 cycles without significant loss of adsorbent activity.

Summary: A magnetic chitosan grafted-benzaldehyde (CS-BD/Fe3O4) was synthesized as a promising adsorbent for acid red 88 (AR88) dye removal. The variables influencing AR88 dye adsorption were studied using the Box-Behnken design, and the adsorption profiles were described by the Temkin model and pseudo-first-order kinetics model. The CS-BD/Fe3O4 demonstrated high adsorption capacity (154.1 mg/g) and various mechanisms, such as electrostatic attraction and π-π interaction, were involved in the adsorption process. This research highlights the potential of CS-BD/Fe3O4 as an effective bio-adsorbent for azo dye removal from contaminated wastewater.

Summary: Microalgae has attracted attention as an alternative feedstock for biofuel production, especially when combined with genetic modification strategies for enhanced lipid productivity. As a potential sustainable energy source, microalgae utilize solar energy and carbon dioxide to produce energy-rich compounds that can be further converted into various types of biofuels. Biodiesel from transesterification of triacylglycerols is considered the most sustainable replacement for fossil-based diesel fuel. However, challenges in productivity, production cost, and upscaling technology hinder the commercialization of microalgae-based biofuel. This review article provides an overview of microalgae classification, factors affecting growth during cultivation, upstream processing, downstream processing, genetic modification strategies, and discusses the current challenges and future prospects of microalgae-based biofuels, including sustainability, industry status, and risks and legislation considerations.

Summary: In this study, nitrogen-doped graphene nanosheets (NGS) were synthesized for efficient removal of diclofenac sodium (DFS) from water. The NGS showed a removal efficiency of 99.8%, an adsorption capacity of 278 mg g(-1) for DFS within 30 minutes, and excellent reusability for up to 5 cycles. The adsorption process followed the pseudo-second order kinetic model and Langmuir isotherm model, as confirmed by X-ray photoelectron spectroscopy (XPS) and FTIR studies. The cytotoxicity assay on Chlamydomonas sp. indicated the non-toxic nature of NGS. This work highlights the promising application of NGS as a cost-effective adsorbent for water remediation in resource-poor environments, aligning with UN-Sustainable Development Goal-6.

Summary: This study successfully synthesized functionalized algal biochar-clay composite (FBKC) and extensively evaluated its sorption performance towards norfloxacin (NFX) antibiotic and crystal violet dye (CVD) in both batch and continuous flow systems. Characterization techniques showed that FBKC had a significantly increased surface area and well-developed pore structure compared to the precursors. FBKC exhibited a high maximum sorption capacity for both NFX and CVD, and the fitting of experimental data to Freundlich and Clark models suggested multi-layer sorption of NFX/CVD molecules. Mechanistic studies revealed multiple mechanisms involved in NFX/CVD sorption onto FBKC, and the estimated low cost and superior sorption capacity make FBKC an efficient sorbent for emergent water pollutants.

Summary: In this study, a constructed photosynthetic consortium was investigated for its carbon capture and nutrient removal capabilities. The consortium showed efficient removal of inorganic and organic carbon species, but suboptimal removal of phosphate and total nitrogen. However, nitrite and ammonia were almost completely depleted, indicating successful nitrogen removal. Real-time monitoring of the consortium's biodiversity and biofilm formation provided valuable insights into nutrient and carbon flux. This study highlights the importance of cultivating biodiverse and adaptable consortia for industrial applications and the utility of real-time monitoring for optimal performance.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
