This study focuses on the synthesis of activated carbon through the calcination method, designed as an absorber for iron (Fe) and copper (Cu) metals in well water previously investigated. The raw material utilized for activated carbon production is rice husk waste, with variations in calcination temperatures set at 700°C, 800°C, and 900°C. The characterization of the activated carbon involved XRD testing for phase analysis, SEM-EDX analysis on rice husk to discern the morphology and composition of the activated carbon components, and absorption performance analysis using AAS. The XRD testing results revealed an amorphous shape in samples calcinated at 700°C and 800°C. However, the 900°C samples exhibited the formation of the tridymite phase. SEM-EDX results showcased an increased surface area and a more compact pore structure, attributed to high-temperature calcination. AAS testing results indicated an improvement in the absorption capacity of iron (Fe) and copper (Cu) metals. In this research, each 4 g activated carbon sample proved most effective at reducing the initial iron (Fe) metal content from 8.06 mg/L to <0.009 mg/L, achieving an impressive 99.88% absorption. Furthermore, with every 2 g sample, copper (Cu) metal was efficiently absorbed, reducing the initial content from 3.99 mg/L to <0.006 mg/L, achieving a notable 99.85% absorption.

“…According to recent reports, , about 2.2 billion people worldwide have no access to safe water. Although traditional water treatment technologies, including thermal distillation, adsorption, reverse osmosis, and ion exchange, have been widely used to purify wastewater, these measures have their inherent limitations, such as the tedious operation process, the high cost for equipment investment, the massive energy demand, and the secondary pollution. Such drawbacks make these conventional methods inconvenient for implementation in underdeveloped areas.…”

The interfacial solar-driven evaporation has been deemed as an environmentally friendly approach for freshwater generation. Nevertheless, there is still a challenge to obtain solar evaporators with efficient vapor production from low-cost and renewable biomass through a simple preparation process. Herein, the JUJUNCAO stem was selected as the substrate material, and a kind of interfacial solar-driven evaporator with natural two-phase composite structures and inherent ultralow water vaporization enthalpy was constructed by a dip-coating process. The natural two-phase composite structures were utilized as independent functional partition: the low-tortuosity and hydrophilic vascular bundles served as hierarchical channels for rapid water transportation and continuous steam escape, and the honeycomb-like parenchyma cells were considered natural heat insulators for effective thermal management. Furthermore, the JUJUNCAO stem exhibited inherent ultralow water vaporization enthalpy which was only 1.15 kJ g–1. Benefiting from the natural two-phase composite structures of functional partition and inherent ultralow water vaporization enthalpy, the C-Js evaporator could achieve an evaporation rate of 2.77 kg m–2 h–1 with an efficiency of 85.6% under 1 sun illumination. Meanwhile, the C-Js exhibited a stable and ideal evaporation performance and metal ion rejection behavior in the actual brine desalination process. Owing to the cost-effective and simple pretreatment process, the C-Js evaporator has the potential for freshwater generation in undeveloped areas.

“…Consequently, the imperative to expeditiously investigate methodologies for the removal of these ions from water effluents has become a preeminent priority, in order to safeguard the reservoirs of the future 2 – 5 . For this purpose, multiple methods have been applied and investigated such as reverse osmosis 6 , ion exchange 7 , and chromatography 8 . The above-mentioned methods have extortionate costs and complexity; thus, other alternatives such as adsorption 9 , chemical methods 10 , biological methods 11 , and nanotechnology 12 have been heavily investigated 13 – 15 .…”

The challenges in water treatment include the need for efficient removal of pollutants like nitrate, which poses significant environmental and health risks. Alumina's significance lies in its proven effectiveness as an adsorbent for nitrate removal due to its high surface area and affinity for nitrate ions. This study delves into the synthesis of differen nano-sized γ-alumina (γA1-5) employing diverse precursors and methods, including nepheline syenite, lime, aluminum hydroxide, precipitation, and hydrothermal processes at varying reaction times. Simultaneously, magnetite (Fe3O4) nanoparticles and magnetite/γ-alumina nanocomposites (Fn/γA5) were synthesized using the co-precipitation method with varying weight ratios (n). Our primary objective was to optimize γ-alumina synthesis by comparing multiple methods, shedding light on the influence of different precursors and sources. Hence, a comprehensive adsorption study was conducted to assess the materials’ efficacy in nitrate removal. This study fills gaps in the literature, providing a novel perspective through the simultaneous assessment of magnetite/alumina nanocomposites and pure alumina performance. Structural and morphological properties were studied employing XRD, FT-IR, FESEM, EDX, XRD, and VSM techniques. The conducted experiments for γA5, F5/γA5, and F10/γA5 nanocomposites showcased the optimum pH of 5 and contact time of 45 min for all samples. The influence of nitrate’s initial concentration on the removal percentage was investigated with initial concentrations of 10 ppm, 50 ppm, and 100 ppm. γA5, F5/γA5 and F10/γA5 nanocomposites had 17.3%, 55%, and 70% at 10 ppm, 18%, 55.16%, and 74% at 50 ppm, and 8.6%, 53.1%, and 63%, respectively. The results highlighted that F10/γA5 can be used as a remarkable adsorbent for wastewater treatment purposes.
