“…Heavy metal discharged from various industries and scrap yards threatens the human population and environment [41]. The potential anthropogenic sources of heavy metals in the environment include agricultural, industrial waste, inland effluent, wastewater irrigation [42,43], mining, and electroplating [44]. However, high levels of heavy metals in the environment can have hazardous consequences on people, animals, and plants [14,45].…”

Heavy metal pollution has posed a severe danger to environmental stability due to its high toxicity and lack of biodegradability. The present study deals with the appraisement of tolerance shown by various bacteria in varied copper and iron concentrations. Among the 20 isolates, four isolates, GN2, SC5, SC8, and SC10, exhibiting more significant iron and copper tolerance, were selected and identified by 16 S ribosomal ribonucleic acid (rRNA) gene sequence analysis as Pantoea agglomerans strain GN2, Pantoea sp. strain SC5, Bacillus sp. strain SC8 and Priestia aryabhattaistrain SC10. The minimum inhibitory concentration of molecularly identified strains revealed that P. agglomerans strain GN2 showed tolerance to iron sulfate and copper sulfate upto 600 and 400 µg/mL, whereas Bacillus sp. SC8 (OQ202165) showed tolerance of 700 and 250 µg/mL were tolerant to iron sulfate and copper sulfate up to 700 and 150 µg/mL, respectively. Pantoea sp. strain SC5 showed significant tolerance to both heavy metals. The isolates were further studied for their ability to grow at varying temperatures and pH ranges. Most of the isolates showed optimal growth at 37°C and pH 7. However, Pantoea sp. SC5 was competent to have prominent growth at 45°C and pH 8.0. Microbial remediation, which is eco‐friendly, has proven the most effective method for bioremediation of heavy metal‐contaminated environments. Using heavy metal‐resistant bacteria for microbial remediation of iron and copper‐contaminated environments could be a viable and valuable strategy. These isolates could also be used to decontaminate heavy metal‐polluted agricultural soils.

“…Furthermore, heavy metals are the most commonly found contaminants in wastewater that are a public-health concern due to their high toxicity [ 10 ]. Sources of heavy-metal pollution include mining waste [ 11 , 12 ], water leaks in landfills [ 13 ], municipal wastewater, and industrial wastewater [ 14 ], especially from industries, such as electroplating and electronic metal fabrication [ 15 ]. Heavy metals are necessary for human metabolism; however, high concentrations can be toxic and dangerous to humans [ 16 , 17 ].…”

A Critical Review of Snail Shell Material Modification for Applications in Wastewater Treatment

2023

Sea material is becoming increasingly popular and widely used as an adsorbent in wastewater treatment. Snail shell, a low-cost and natural animal waste material, has been shown to have a high calcium content (>99%) and a large potential surface area for the development of sustainable adsorbents. This paper presents a novel synthesis of methods for using snail shell absorbent materials in the treatment of wastewater containing heavy metals, textile dyes, and other organic substances. Modified biochar made from snail shells has gained popularity in recent years due to its numerous benefits. This paper discusses and analyzes modification methods, including impregnating with supplements, combining other adsorbents, synthesis of hydroxyapatite, co-precipitation, and the sol–gel method. The analysis of factors influencing adsorption efficiency revealed that pH, contact time, temperature, initial concentration, and adsorbent dose all have a significant impact on the adsorption process. Future research directions are also discussed in this paper as a result of presenting challenges for current snail adsorbents.

“…There is cause for concern regarding the release of toxic metals into water bodies. Metal ions, for example, Pb(II), Cr(III), Hg(II), Cd(II), Zn(II), Co(II), and Ni(II) are known to be poisonous when they discharged into the environment in amounts that pose significant human health risks [4][5][6]. These metals frequently accumulate in various organs and tissues of living things, causing a variety of impairments and diseases.…”

Facile synthesis and characterization of Fe3O4/analcime nanocomposite for the efficient removal of Cu(II) and Cd(II) ions from aqueous media

In the water purification field, heavy metal pollution is a problem that causes severe risk aversion. This study aimed to examine the disposal of cadmium and copper ions from aqueous solutions by a novel Fe3O4/analcime nanocomposite. A field emission scanning electron microscope (FE-SEM), Fourier transform infrared spectroscopy (FT-IR), and X-ray diffraction were used to characterize the synthesized products. The FE-SEM images showed that the analcime and Fe3O4 samples consist of polyhedral and quasi-spherical shapes with average diameters of 923.28 and 28.57 nm, respectively. Besides, the Fe3O4/analcime nanocomposite consists of polyhedral and quasi-spherical shapes with average diameters of 1100.00 nm. The greatest uptake capability of the Fe3O4/analcime nanocomposite toward the copper and cadmium ions is 176.68 and 203.67 mg/g, respectively. The pseudo-second-order kinetic model and Langmuir equilibrium isotherm best describe the uptake of copper and cadmium ions using the Fe3O4/analcime nanocomposite. The uptake of copper and cadmium ions using the Fe3O4/analcime nanocomposite is exothermic and chemical in nature.
