“…self-assemble to generate intermediate crystallized nano rodlike morphology (nesquehonite), which are thermodynamically stable at room temperature even though these nanorods can be dissolved under hydrothermal process and re-form flakeslike morphology. Depending upon the reaction conditions (Temperature, Time of autoclave), flake-like morphology can be preserved [103] or converted to different morphologies. [104] According to our reaction conditions, we obtained nanoflakes, but still, the flake morphologies are slightly different when compared with SEM images of other literature.…”

“…[104] According to our reaction conditions, we obtained nanoflakes, but still, the flake morphologies are slightly different when compared with SEM images of other literature. [101,[103][104][105][106] Most intermediate chemical compounds decompose to magnesium oxide (MgO) by the calcination process. Hence the final flakelike product almost contains MgO as its chemical content.…”

Phosphate containing untreated wastewater, discharged into water bodies, can cause eutrophication, leading to harmful effects on the ecosystem and human health. This study focuses on a simple, low-cost, and novel approach towards removing excess phosphate ions from aqueous solutions by adsorbing on onto two-dimensional (2-D) magnesium oxide nano-flakes (MONFs). The phosphate removal efficiency was tested with different concentrations of phosphate solutions (2-25 mg L À 1 ), pH levels (3-11), adsorbent dosages (0.025-0.250 g), and contact times (10-50 min). The maximum phosphate removal percentage of 100 % was obtained with 50.0 mL of 3 mg L À 1 phosphate solution using 0.125 g of the synthesized MONFs with a phosphate absorption capacity of 29.9 mg g À 1 . Moreover, the adsorption data fit with the Freundlich isotherm, with an R 2 value of 0.952. The adsorption kinetic data follow the pseudosecond-order model, with an R 2 value of 0.995, suggesting that the adsorption process is chemisorption.

“…On the other hand, the removal capacity of methylene blue goes increase with solution pH related to the more positive charge on MgO at high pH and relatively repulsion between similar charges. This difference in adsorption ability for each dye is related to the nature of the pollutant, and surface charge on MgO [24,41].…”

The adsorption of dyes from the industrial influent has attracted great interest to overcome water pollution. In this work, we carefully investigated the growth process of hierarchical MgO microspheres and the difference in the corresponding removal behavior towards two dyes: anionic methyl orange and cationic methylene blue. The MgO microspheres were formed by the self-assembly of thin nanosheets following the reaction time and exhibited the maximum removal capacities are 940.14 mg g-1 for methyl orange and 354.00 mg g-1 for methylene blue. The anionic methyl orange and cationic methylene blue adsorption follow the pseudo-second-order kinetic model, Freundlich isothermal model. The difference in the removal behavior towards two dyes is strongly related to the surface charge of MgO and the charge of pollutants. This work will benefit design and improvement in the removal performance of novel porous adsorbents.

This century is struggling with the issue of environment friendly management of the pollutants which are contaminating the environment. One of an ecofriendly and economically feasible method is the bioremediation of pollutants using bio nanoparticles. Nanobioremediation is a highly studied and explored area of remediation of contaminants using nanotechnology. Nanoparticles used for bioremediation are biologically synthesized from plant extracts, fungi and bacteria. These biogenic nanoparticles when applied to environmental contaminants had shown very promising results. Based on the various studies the bioremediation of pollutants using biosynthetic nanoparticles is emerging as a very promising and sustainable method of environment cleanup. This review focuses on the synthesis of bio-nanoparticles and their use in cleaning the environment.
