“…There has been considerable discussion about bioremediation techniques in terms of tackling the environmental and drinking water problems around the world (Palit, 2020). Heavy metals have also been removed using various technologies involving nanomaterials to offer a greener environment as well as a reduced human health risk, as discussed by previous researchers (Dhiman et al., 2021). Although various technologies have been employed to remove As, adsorption is the most effective method.…”

In the advancing generation, commercialization and industrial development are on the incessant proliferation. Due to this unremitting need for development, the danger to the biological health of the environment is on the assurgent rise. Many “clean and green” industrial protocols have been generated and taken into purview but has been ineffective in keeping abreast with the ever‐growing pace of environmental threats. Technology in today's world has been the game changer in revolutionizing the way humans live their lives today but at the same time, has also become the greatest source of threat to the very sustainability of the planet. Thus, newer technological enhancements have been initiated to compensate for the harm to the environment. Of these, green and sustainable nanotechnological methodology and tools to be used as zero waste tools have been developed to efficiently beat the crisis of the hour. For example, the development of various nano‐based zero‐waste tools to the introduction of nanotechnology in various industries like automobiles, water, agriculture, and so on, has changed the way sustainable development has been adopted. This article aims to enhance the success of nanotechnology in the various sustainable developments done in industrial fields to cope up with the need of a “clean and green” environment.

“…To tackle this issue, it becomes imperative to explore research avenues for environmental remediation methods that are both economical and environmentally benign. Several works have suggested that nanotechnology is one of such avenues [5,6]. The creation of novel materials with dimensions in the nano-scale range is a component of nanotechnology.…”

This study compared the effectiveness of bare zero-valent iron nanoparticles (B-nZVI) and starch-stabilized zero-valent iron nanoparticles (S-nZVI) in immobilizing Pb and Cd from lead-acid battery waste soils. Both B-nZVI and S-nZVI were prepared in almost identical manner using the technique of reducing ferric chloride with sodium borohydride. X-ray diffraction (XRD) and dynamic light scattering (DLS) analyses confirmed that polydisperse B-nZVI and S-nZVI were synthesized. XRD and DLS analyses showed that B-nZVI and S-nZVI had different surface properties. To assess the immobilization capability of B-nZVI and S-nZVI, a composite soil sample was collected from an automobile lead-acid battery waste dumpsite. The soil sample had a pH of 3.85 and Pb and Cd levels of 16,674 mg/kg and 41 mg/kg, respectively. Single extraction procedures using 0.01M CaCl2, 0.1 M HCl, and 0.05 M EDTA were used to simulate phytoavailable Pb and Cd in the soil studied. Batch immobilization analysis showed that Cd was mobile in the control but immobile in B-nZVI and S-nZVI treated soils. Pb was however not immobile in either the control or treated soils. The mobility of Pb however decreased with increasing doses of S-nZVI and 0.003 g of S-nZVI was needed to make Pb completely immobile in soil. Batch immobilization also showed that S-nZVI was 1.8-2.49 times more efficient in immobilizing Pb than B-nZVI. Simulated phytoavailability of Pb was in the order of EDTA > HCl > CaCl2 > H2O while simulated photoavailable Cd was in the order of HCl > EDTA > H2O > CaCl2.
