“…leaves' extracts. The reducing ability of the plant extract was investigated using a ferric reducing antioxidant power (FRAP) assay and color development tests as described by Manquián et al 33 and Wei et al 34 (Text-S3 †). During the FRAP assay, the ability of the plant extract, to reduce Fe 3+ to Fe 2+ is measured at an absorbance of l ¼ 593 nm by producing a blue complex with tripyridyltriazine (TPTZ).…”

A novel hybrid nanomaterial, nanoscale zero-valent iron (nZVI)-grafted imogolite nanotubes (Imo), was synthesized via a fast and straightforward chemical procedure. The as-obtained nanomaterial (Imo-nZVI) was characterized using transmission electron microscopy (TEM), electrophoretic mobility (EM) and vibrating sample magnetometry (VSM). The prepared Imo-nZVI was superparamagnetic at room temperature and could be easily separated by an external magnetic field. Sorption batch experiments were performed in single- and multicomponent system and showed that Hg2+ and Pb2+ could be quantitatively adsorbed at pH 4.0 with maximum adsorption capacities of 62.3 and 73.8 mg·g− 1, respectively. It was observed that the functional groups in Imo-nZVI interact preferentially with analytes according to Misono Softness parameter. The higher performance of Imo-nZVI compared with Imo and nZVI is related to the increased adsorption sites in the functionalized nanomaterial. The sorption equilibrium data obeyed the Langmuir model, while kinetic studies demonstrated that the sorption processes of Hg2+ and Pb2+ followed the pseudo-second-order model. This study suggests that the Imo-nZVI composite can be used as a promising sorbent and provides a simple and fast separation method for the removal of Hg and Pb ions from contaminated water.

“…A threshold redox potential is essential for efficient reduction of metal ions in the precursor solution [71]. Some studies have reported analyzing the reducing capacity of aqueous plant extracts by FRAP assay (ferric reducing antioxidant power assay) and estimation of total phenol content by Folin-Ciocalteu reagent [72].…”

At present, natural resources are very limited and inadequate for increasing global population along with uncontrollable environmental pollution. The development of advanced eco-friendly technology and pollution free environment is very necessary for the current situation. Nanotechnology is playing a vital role in the development of "cleaner" environment and "greener" technologies for sustainable livelihood and environment. Nanotechnology is involved in many sectors like pharmaceuticals, agriculture, food, energy, environment, cosmetics, electronics, chemicals, and so on. There are many consumer products containing nanomaterials available in the market for ready use by human beings. Hence, human exposure to nanomaterials is possible to occur during processing at occupational level and personal usage at consumer level. At present, nanotechnology is a promising tool as it has high performance and is cost-effective in
