“…In the case of dye removal, magnetic nanoparticles have been proved to be proper candidates (Lohrasebi and Koslowski 2019). Nanoadsorbents such as silica gel, activated alumina, clays, limestone, chitosan, activated carbon, and zeolite are cost-effective and profitable options for eliminating the contaminating agents during water purification process (Ali et al 2020).…”

Nanotechnology is one of the most emerging fields of research within recent decades and is based upon the exploitation of nano-sized materials (e.g., nanoparticles, nanotubes, nanomembranes, nanowires, nanofibers and so on) in various operational fields. Nanomaterials have multiple advantages, including high stability, target selectivity, and plasticity. Diverse biotic (e.g., Capsid of viruses and algae) and abiotic (e.g., Carbon, silver, gold and etc.) materials can be utilized in the synthesis process of nanomaterials. "Nanobiotechnology" is the combination of nanotechnology and biotechnology disciplines. Nano-based approaches are developed to improve the traditional biotechnological methods and overcome their limitations, such as the side effects caused by conventional therapies. Several studies have reported that nanobiotechnology has remarkably enhanced the efficiency of various techniques, including drug delivery, water and soil remediation, and enzymatic processes. In this review, techniques that benefit the most from nano-biotechnological approaches, are categorized into four major fields: medical, industrial, agricultural, and environmental.

“…Zeolites are three-dimensional, crystalline microporous materials, having well-defined structures of voids and conduits of distinct size, which is easily accessible through pores of well-defined molecular dimensions that hold aluminum, silicon and oxygen in their normal framework [ 92 , 93 , 94 ]. Zeolites are found naturally as silicate minerals and can also be prepared synthetically as magnetically modified zeolite, and bio-zeolite, etc.…”

Clean and safe water is a fundamental human need for multi-faceted development of society and a thriving economy. Brisk rises in populations, expanding industrialization, urbanization and extensive agriculture practices have resulted in the generation of wastewater which have not only made the water dirty or polluted, but also deadly. Millions of people die every year due to diseases communicated through consumption of water contaminated by deleterious pathogens. Although various methods for wastewater treatment have been explored in the last few decades but their use is restrained by many limitations including use of chemicals, formation of disinfection by-products (DBPs), time consumption and expensiveness. Nanotechnology, manipulation of matter at a molecular or an atomic level to craft new structures, devices and systems having superior electronic, optical, magnetic, conductive and mechanical properties, is emerging as a promising technology, which has demonstrated remarkable feats in various fields including wastewater treatment. Nanomaterials encompass a high surface to volume ratio, a high sensitivity and reactivity, a high adsorption capacity, and ease of functionalization which makes them suitable for application in wastewater treatment. In this article we have reviewed the techniques being developed for wastewater treatment using nanotechnology based on adsorption and biosorption, nanofiltration, photocatalysis, disinfection and sensing technology. Furthermore, this review also highlights the fate of the nanomaterials in wastewater treatment as well as risks associated with their use.

“…Removing salinity using agricultural wastes of the normal size and its natural material reached to 8%, by activating these wastes, the removal of salts reached to15% (Kim et al, 2017), while using these wastes as a carbon nanosize, the removal of salts reached to more than 99% (Butt, 2020). Nanoparticles are considered most significant and appropriate for water treatment and purification as they are highly reactive, have great surface area to volume ratio and have a good affinity for target substances and their extremely small size makes them most appropriate purification agents (Ali et al, 2020 andButt, 2020).…”

The leather industry has a high economic return, but also has harmful effects on society and the environment. One of the most important of these harmful effects is the problem of salinity of water bodies, soil and groundwater. The main objective of the research is to improve the quality of industrial effluent for safe use in agricultural purposes. Green tea (GT), pomegranate peels (PP) and potato peels (Po) were washed with hot distilled water at 85°C several times until its color fades and dried in oven at 105°C and then burned at 400°C, the dried wastes were chemically activated with 1.0 M sulphuric acid for three hours and washed several times with distilled water and dried again. The obtained carbon was ground to very fine powder and characterization by transmission electron microscopy. Nanoparticles size of green tea spoil carbon(GTCn), pomegranate peels carbon (PPCn) and potato peels carbon (PoCn) ranged between 1-50 nm. The result indicated that the effect of green tea spoil carbon nanoparticles at three layers (GTCn3) in addition to potato peels carbon nanoparticles at one layer (PoCn) on removal of salinity from tannery effluent was 99.85% and the parameters of EC, TDS, soluble cations and anions were less than permissible limits for discharge into water bodies. The agricultural residues carbon nanoparticles adsorb the hateful odor, remove yellow color and remove the turbidity.
