“…It is observed from the IR spectra that the band observed between 750 -650 cm -1 is attributed to symmetric T -O -T vibration (where T = Si or Al) which is on agreement with values reported for NaA zeolite in previous work [25]. The broad band between 4000 -3000 cm -1 might be attributed to the vibration stretching of hydroxyl group of water molecules and amines present in the pores of the zeolites [26,27] while the band observed at 957 cm -1 is related to HS [25]. However, the band observed at 1650 cm -1 might be attributed to zeolitic water [1,] while the peaks observed at 1450 cm -1 might be due to excess alumina present in the pore has also reported by Byrappa and Suresh Kumar [26].…”

Zeolites NaA is one of the most valuable synthetic zeolites widely used as ion-exchange material, catalysts, and adsorbents in industry. There is therefore need to adopt a more energy-efficient route for its synthesis from low-cost and sustainable raw materials. In this present work, zeolites Na-A was synthesized from natural kaolinite clays obtained from three selected regions (Ikere, Okpella and Kankara) in Nigeria. The as-received kaolinite clays (IKclay, OKclay and KAclay) were initially beneficiated thoroughly to obtain pure powders (˂75 μm). The processed kaolinite clay powders were then subjected to heating in a muffle furnace at 850oC for 3 h at a heating rate of 10oC/min to convert the kaolinite clays to their respective metakaolins. The obtained metakaolins were then reacted with NaOH solutions at varying concentrations of 3.0 and 4.0M respectively using a low temperature hydrothermal transformation to obtained Zeolites Na-A powders. The obtained zeolites were then analyzed by scanning electron microscopy (FESEM), energy dispersive spectroscopy (EDS) and Fourier-transform infrared spectroscopy (FT-IR). The results showed that zeolite NaA is produced with mixture of hydroxysodalite (HS) while the EDS revealed the presence of Si, Al, O and Na indicating chemical constituents of typical zeolite NaA. All the tested kaolinite clays are therefore suitable for preparation of zeolite NaA as cheaper source of silica and aluminum.

“…The thermal stability of dried fish scale adsorbent was explored by performing thermogravimetric analysis (Figure 2). There was a slight decrease in the initial phase of 0-100 C which might be due to the removal of week-bonded water molecules within the materials 33 while the subsequent sharp drop in weight between 200 and 700 C could be attributed to the elimination of organic matter in fish scales and dehydration of HPO 4 2À yielding hydroxyl apatite (HAp) (Ca 5 (PO 4 ) 3 (OH)). 10 Next, the crystallinity and phase purity of adsorbents were examined using XRD and the obtained diffraction patterns corresponding peaks were formed at 2θ = 26.1 , 34.6 , 39.9 , 46.9 , 49.5 , and 53.4 , respectively.…”

Pollution of water by organic and inorganic contaminants is a serious environmental issue. The primary emphasis of this present investigation was to reduce wastewater pollution and environmental burden related to fish waste disposal. Prime pollutant parameters such as biological oxygen demand (BOD) and chemical oxygen demand (COD) in fish processing effluent were treated by adsorbents produced from waste fish scales viz., dried fish scale adsorbent and fish scale biochar. A control was used and the entire study was carried out in batch mode to assess the influence of adsorbent dosage levels, contact time, and pH conditions. The experiments revealed that prepared fish scale biochar was as effective as control in achieving a significant (p < 0.05) reduction of BOD (87%) and COD (84%) at 150 min treatment time with 0.24 and 0.48 g dosage level. The optimum pH range was found to be 6–8. The experimental data fitted well with pseudo‐second‐order and Langmuir isotherm models (R2 > 0.911). The influence of intraparticle diffusion in adsorption treatment was tested with Weber–Morris plot. The experiments were done in triplicate and all data were statistically tested using MS Excel, IBM SPSS (version 26), and OriginPro software packages.

“…The techniques include the Fenton process [13]; degradation by photocatalytic processes [14][15][16][17][18][19], sono-chemical degradation [20]; photo-Fenton processes [21], chemical coagulation/flocculation, cloud point extraction, ozonation, oxidation, chemical precipitation, nanofiltration, ion exchange, reverse osmosis, and ultrafiltration [22][23][24][25][26], and modified methods such as those combining ultrasound with adsorption-desorption processes [27][28][29][30]. These methods proved to be effective; however, some revealed some limitations in the areas such as high cost of operation, a bulk of chemicals required, and disposal problems due to the accumulation of the bulk of sludge [17,[31][32][33][34]. Among these techniques, adsorption is considered as one of the most efficient mothod for wastewater treatment due to its design and operation simplicity, non-toxic, low cost of adsorbent and high efficiency [3,34].…”

Plant-mediated synthesis of iron oxide nanoparticles has been increasingly drawing attention due to its ecofriendly nature and cost effectiveness. The biosynthesis technique engages plant secondary metabolites such as alkaloids, flavonoids, saponins, phenols, proteins, carbohydrates, glycosides, quinine, steroids, and tannins as reducers and/or stabilizers in the process of forming nanoparticles thereby replacing hazardous chemicals known with physical and chemical methods of nanomaterial synthesis. Biosynthesis method of nano particles has helped to a great extent to overcome some drawbacks, such as high energy and space requirement as well as high cost and hazard associated with various known physical and chemical methods. This work reviewed the biosynthesis of plant mediated iron oxide nanoparticles and their applications in water and wastewater treatment. Much work has been done to explore the effective, safe and cheap method for the dye removal in recent years. However, in future, more methods need to be explored to study and check the removal of dyes from wastewater using plant-mediated iron oxide nanoparticles for safer, cheaper and more efficient performance.
