“…All the reagents used for the analysis were of analytical grade and obtained from Merck and Qualigens brand. Deepa et al [12][13][14] suggested the standard path for comparing the collected sampling data for the water quality index, which was added in the research work [12,13]. Published works were not experimentally dealt with food waste water sources.…”

Bioinorganic chemistry is found as a sizzling field in today’s era. It deals with chemistry amongst the heavy metals with natural resources, i.e., air, soil, water, plant byproducts (foods), and environmental essences. The aim of this research is to determine the concentration of heavy metals present in the food waste water sample and to study the environmental effects of metal ion concentration. To conduct the research work, the physicochemical parameters and levels of five heavy metals of food waste water samples were collected from five sampling points of renowned hotels, restaurants, canteens, and confectionaries of a state of India and assessed using the standard analytical procedure. Sampling was carried out from January 2017 up to December 2017. The physicochemical parameters were determined such as pH, temperature, turbidity, conductivity, total dissolved solids, total suspended solids, total alkalinity, biological oxygen demand, chemical oxygen demand, dissolved oxygen, total organic carbon, sulphate, nitrate, and phosphate. The heavy metal concentration was determined by using the UV-spectrophotometer, and the results were compared with the standards prescribed by the WHO, BIS, ICMR, and municipal authorities. The results obtained in the physicochemical analysis revealed that a few parameters were found beyond limits, and the metal ion concentration (iron and zinc) results were found above the permissible limits set by the CPCB (Central Pollution Control Board), ICMR, BIS, and World Health Organization (WHO), most especially, effluent from point P1. It was concluded that all the effluents required further treatment before releasing them into the water body or land to prevent pollution. The obtained results reveal that waste water used for irrigation and farming of nearby areas and water drained from restaurant kitchens were considerably polluted and not suitable for aquatic organisms, irrigation, and agricultural purposes.

“…12 Adsorbents can be divided into inorganic and organic groups that can be produced by gathering from nature, manufacturing synthetically and collecting from residue or waste streams. For example, activated carbon prepared from peanut shell has been used for Cr(VI) removal, 13 iron oxide nanocomposites for Pb(II), Cd(II), Cr (III) and Co(II) separation 14,15 and iron oxide metal-organic framework for U(VI) and Th(IV) sequestration. 16 Powderous, granular and brous zirconium dioxide have exhibited high Sb(V) adsorption capacities.…”

“…Among these methods, surface adsorption has been widely used due to various advantages such as low cost, easy design and high efficiency [8][9][10][11][12][13][14][15][16]. Many studies have been carried out on the absorption of methylene blue by various adsorbents that can be cited in studies by authors Andreas, Fan, Alehyen Omidi Khaniabadi and Altıntıg such as orange peel [17], tea waste [18], fly ash-based geopolymer [19], aloe vera wastes [5] and magnetic loaded activated carbon adsorbers [6] in 2016-2018. In recent years, the use of nanoparticles, especially magnetic nanoparticles, as adsorbents for the removal of various pollutants, due to the important properties, including easy separation by an external magnetic field, easy synthesis of nanoparticles, high surface area and ease of enhancement, has been found [12,[20][21][22][23]. Recently, many studies have been conducted on ferrite nanoparticles (NP S ) due to important properties such as high surface-to-volume ratio, high stability, recyclability and biocompatibility [24].…”

In this study, the ZnFe 2 O 4 @SiO2@Tragacanth gum magnetic nanocomposite as a novel adsorbent was synthesized and was confirmed by FTIR, XRD, TEM, TGA and VSM methods. Then, the prepared nanocomposite has been tested for the removal of methylene blue dye from aqueous solution for adsorption process, and the effect of various parameters including pH (2-12), adsorbent dosage (0.2-2 g/L), temperature (15-45 °C), initial dye concentration (10-60 mg/L) and contact time (5-120 min), also its isotherms and kinetics has been studied. The results showed that the optimum pH, contact time, initial dye concentration, adsorbent dosage and maximum adsorption capacity were 8, 60 min, 60 mg/L, 0.2 g/L and 109.37 mg/g, respectively. Furthermore, the experimental data determined that the adsorption of methylene blue dye interpreted the Freundlich isotherm (R 2 = 0.979) and the pseudosecond-order kinetics model (R 2 = 0.998). Also, the thermodynamic parameters of the absorption system, such as changes in enthalpy (ΔH = + 9.36 kJ/mol), entropy (ΔS = + 40.72 J/mol k) and Gibbs free energy (ΔG = − 3.5 kJ/mol), were measured and showed that adsorption process of ZnFe 2 O 4 @SiO2@Tragacanth gum magnetic nanocomposite was endothermic and spontaneous process. As a result, due to high adsorption capacity, environment friendly, low cost, rapid extraction and non-toxicity, the ZnFe 2 O 4 @SiO2@TG magnetic nanocomposite can be used as an effective adsorbent for methylene blue removal from aqueous solutions.
