    Abstract A novel green synthesized iron-aluminum nanocomposite was prepared and characterized by FESEM, FTIR, EDX, XRD, BET, DSC and TGA analysis. The clove extract acting as both reducing and surface coating agent was optimized based on its maximum total flavonoid content (TFC) and total polyphenolic content (TPC). Fluoride adsorption studies was performed at 298K, 303K and 313K within the range of 10-40 mg/L fluoride solution for kinetic and isotherm studies. Maximum adsorption capacity of 42.95 mg/g was obtained for 0.25 g/L adsorbent dosage. Moreover fluoride adsorption obeyed pseudo second order kinetic model whereas the process was multistage diffusion controlled. Langmuir isotherm model best fitted the equilibrium data with monolayer adsorption capacities of 25.09, 26.08 and 28.07 mg/g at 298, 303 and 313K respectively. The findings confirmed that the fluoride adsorption process followed ion exchange mechanism with the surface hydroxyl groups. The prepared nanocomposite was utilized for treating fluoride contaminated water samples from north-east regions of India which showed efficient removal percentage.

    Abstract Green chemistry has been proven to be an efficient route for nanoparticle synthesis. Plant extract based green synthesis of various nanoparticles is extensively studied since the last decade. This paper “Green synthesis and environmental application of Iron-based nanomaterials and nanocomposite: A review” unveils all the possible greener techniques for the synthesis of iron-based nanoparticles and nanocomposites. The use of different plant sources, microorganisms, and various biocompatible green reagents such as biopolymers, cellulose, haemoglobin, and glucose for the synthesis of iron nanoparticles reported in the last decade are summarized. The microwave method, along with hydrothermal synthesis due to their lower energy consumption are also been referred to as a green route. Apart from different plant parts, waste leaves and roots used for the synthesis of iron nanoparticles are extensively briefed here. This review is thus compact in nature which covers all the broad areas of green synthesis of iron nanoparticles (NPs) and iron-based nanocomposites. Detailed discussion on environmental applications of the various green synthesized iron NPs and their composites with performance efficiency is provided in this review article. The advantages of bimetallic iron-based nanocomposites over iron NPs in various environmental applications are discussed in detail. The hazards and toxic properties of green synthesized iron-based NPs are compared with those obtained from chemical methods. The prospects and challenges section of this article provides a vivid outlook of adapting such useful technique into a more versatile process with certain inclusions which may encourage and provide a new direction to future research.

    Abstract Iron nanoparticles (NPs) were prepared via Clove extract mediated green synthesis. Iron NPs were immobilized in flat asymmetric polymeric pH responsive PVDF-co-HFP membranes prepared by blending of Polyethylene glycol methyl ether (PEGME)(Mw = 5000 g/mol) and Humic acid (HA). Iron NPs dispersed in pH responsive polymeric membrane in different weight percentage (0.01, 0.1 and 1) imparted catalytic effect in reducing nitrobenzene to aniline as well as enhanced fluoride rejection by dead end filtration experiment. Both the process of NB reduction and fluoride rejection was dependent on pH responsiveness of the membrane. High performance liquid chromatography (HPLC) analysed formation of aniline and nitrobenzene at different ultra-filtration time. Aniline formation of 15 ppm was found to be highest at pH3 and lowest of 12.8 ppm at pH7 for 0.01 wt% iron NPs impregnated membrane at end of 50 min. Aniline formation increased for pH12 than pH7 due to pH responsiveness. Fluoride rejection was studied on optimized wt% of iron NPs from NB reduction experiments with different pH of fluoride solutions. In order to maximize the Aniline formation and Nitrobenzene reduction, the variables (time, pH and wt% of NPs) was optimized using Design expert software 9.0 TRIAL through ANOVA (analysis of variance) using the combination of response surface methodology (RSM) and central composite design (CCD). The optimization study showed negligible error with experimentally obtained values at optimized conditions for maximizing NB reduction (error 3.37%) and aniline formation (error 3.93%).

    Abstract This work focuses on the removal of cyanide, chemical oxygen demand (COD), biological oxygen demand (BOD), and chloride from biological oxidation treated (BOT) effluent of the steel industry by integrated ozonation assisted electrocoagulation method. The removal efficiency of the pollutants was found to be inefficient when the electrocoagulation or ozonation process was performed separately. However, a combination of ozonation and electrocoagulation gives a highly satisfactory result. Such an integrated approach for the treatment of BOT effluent has not been previously investigated. The effects of operating variables viz. ozone generation rate, current density, and analysis time on pollutant removal were primarily analyzed for the hybrid process. The experimental operating condition was optimized and was seen that ozone generation rate of 1.33 mg s⁻¹, ozonation time of 40 min, a current density of 100 A m⁻², and electrolysis time of 30 min were sufficient for reducing the pollutant concentration below its permissible limits. The removal efficiencies of the combined process at optimum conditions were 99.8%, 94.7%, 95%, and 46.5% for cyanide, COD, BOD, and chloride ions, respectively. A kinetic study was performed for the degradation of the pollutants during ozonation. The pseudo-first-order kinetic model was found to be best suited for the analysis with the highest R² value of 0.99 for cyanide, COD, BOD, and chloride, respectively. The mass transfer study conducted further showed that the volumetric mass transfer coefficient, Kₗa, was increased with that of the ozone generation rate. Cost estimation of the hybrid process was done and compared with that of the other reported integrated process.
