This work prepared a composite of orange peels magnetic activated carbon (MG-OPAC). The was categorized by X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), Brunauer-Emmett-Teller (BET), Energy-dispersive (EDX), Scanning Electron Microscopy (SEM) and vibrating-sample magnetometer (VSM) analyses. MG-OPAC showed the surface area (155.09 m2/g), total volume pores (0.1768 cm3/g), mean diameter (4.5604 nm). saturation magnetization (Ms = 17.283 emu/g), remanence (Mr 0.28999 emu/g) coercivity (Hc 13.714 G) were reported for MG-OPAC. Likewise, at room temperature, in super-paramagnetic state, which could be collected within 5 S (< S) with an outside field. Influence time contact, absorbent dose, starting concentration Cr6+ ions, pH tested to adjust absorption process. behavior hexavalent chromium investigated Langmuir (LIM), Freundlich (FIM) Temkin (TIM) isotherm models (IMs). Applicability LIM specifies that ions procedure may monolayer absorption. maximum capacity (Qm) premeditated 277.8 mg/g. Similarly, process different kinetic like intraparticle diffusion (IPDM), pseudo-first-order (PFOM), Elovich (EM), pseudo-second-order (PSOM), Film (FDM). PSOM best fitted experimental results R2 ranging between 0.992 1.

Heavy metal especially nickel (Ni(II)) is the most pernicious kind of pollution since it both poisonous and difficult to break down in nature can cause many human disorders diseases. The monitoring removal Ni(II) ions optically required enhance quality water make appropriate for drinking as well other uses around residence. Therefore, goal current work was synthesize ligand imprinted composite adsorbent (MCA) utilize an monitor remove from water. Based on findings gathered, MCA that synthesized had a large particle size with high surface area even after impregnation. enhanced significantly color contact ion limit detection at 0.35 µg/L. maximum level eliminated (99%) when pH adjusted 5.50. Langmuir model also used study adsorption equilibrium data capacity 167.55 mg/g. Additionally, method selectively detect presence diverse ions. Overall, offers ideal platform on-site heavy ions, resource-limited areas.

Modern agriculture is primarily focused on the massive production of cereals and other food-based crops in a sustainable manner order to fulfill food demands an ever-increasing global population. However, intensive agricultural practices, rampant use agrochemicals, environmental factors result soil fertility degradation, pollution, disruption biodiversity, pest resistance, decline crop yields. Thus, experts are shifting their focus eco-friendly safer methods fertilization ensure sustainability. Indeed, importance plant growth-promoting microorganisms, also determined as “plant probiotics (PPs),” has gained widespread recognition, usage biofertilizers being actively promoted means mitigating harmful effects agrochemicals. As bio-elicitors, PPs promote growth colonize or tissues when administered soil, seeds, surface used alternative avoid heavy In past few years, nanotechnology brought revolution due application various nanomaterials (NMs) nano-based fertilizers increase productivity. Given beneficial properties NMs, these two can be tandem maximize benefits. combinations NMs PPs, synergistic use, its infancy but exhibited better crop-modulating terms improvement productivity, mitigation stress (drought, salinity, etc.), restoration fertility, strengthening bioeconomy. addition, proper assessment necessary before application, dose should applicable without showing any toxic impact environment microbial communities. The combo encapsulated within suitable carrier, this method aids controlled targeted delivery entrapped components increases shelf life PPs. review highlights functional annotation combined manner.
