“…90% cadmium was adsorbed within 2 h at optimum pH [64]. Similar studies reported the removal of lead and nickel from water [88,89]. Studies also indicate that the nanoparticles consumed in the adsorption process are reusable after washing with acids to desorb the adsorbed metal ions [69].…”

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

“…This is due to the synthesis method of the nanoparticles using plant extract, which is a mixture of reducing and stabilizing agents with complex chemistry, producing heterogeneous MNPs and not homogeneous, as is the case when using chemical agents [ 16 ]. Such heterogeneity is an advantage, given that it facilitates the adsorption process by providing active sites for physical exchanges and chemical reactions, as discussed by Es’haghi et al [ 17 ], who synthesized indefinitely shaped and highly agglomerated magnetic iron nanoparticles coated with olive oil.…”

The tanning industry generates effluents with high chromium content, which require treatment prior to discharge into the sewage system. This article explores the use of magnetic magnetite nanoparticles (MNPs) to remove Cr(VI) from aqueous solutions, such as tanning effluents. The MNPs were synthesized by coprecipitation reaction using the Olea europaea extract as a reducing agent. Subsequently, they were characterized by dynamic light scattering spectroscopy (DLS), scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS). MNPs with irregular morphology and diameters ranging from 73.28 to 162.90 nm were obtained. Cr(VI) removal was performed using jar test methodology, and its efficiency was evaluated in the laboratory for different initial Cr(VI) (mg/L) concentration and nanoparticle (g/L) concentration. A kinetic study was developed and indicated that the equilibrium adsorption mechanism corresponds to a pseudo-second-order model. Furthermore, the isotherm analysis revealed that chromium adsorption best fits the Langmuir isotherm. Finally, Cr(VI) removal rates from 85% to 100% were achieved in tanning and retanning effluents.

“…There are also other examples in which the fruit derived materials have been used as support for MNPs. In 2016, Es'haghi and co‐workers developed the synthesis of a sorbent by using Fe 3 O 4 NPs coated with olive oil under dispersive solid‐liquid phase microextraction (DSLME) method [176] . The synthesized sorbent was applied for the adsorption of Ni ions from environmental samples such as potato, mushroom, apple, lettuce, etc.…”

One of the most abundant wastes from all around the world is nutrient resources. Among them, fruits, their extracts, and residues comprise a major portion, which contain many valuable components that get lost during disposal or become burden on the shrinking landfills. These concerns are addressed by seeking sustainable processing methods that would have a minimal environmental impact. The crops contain renewable chemicals which are useful for catalysis, wastewater treatment, or preparation of nanomaterials; there has been an upsurge for the industrial applications of (nano)materials as their environmental and catalytic appliances is a fascinating subject to design cheaper and safer catalytic systems. Due to the excellent chemical properties of the fruit extracts, they have garnered attention as cost-effective catalysts and support materials. This review focuses on the preparation of (nano)materials and their catalytic and environmental applications and highlights the potential appliances and industrial benefits derived from these low-cost renewable and sustainable greener sources thus essentially converting waste into wealth.
