“…Alginic acid is cheap, abundant and can be easily gelated. On the other hand, graphene oxide is a flat molecule with numerous oxygen-containing functionalities, which has a high surface area and acts as a nanofiller [12]. The aerogels formed from this study is promising as it can be used as an adsorbent for different applications.…”

The material graphene is always attracting the researchers and scientists' attention by its fascinating properties. Even it has been a decade after its discovery; scientists are still exploring the hidden potentials of this material. Focus on the current research trend in the field of polymer nanocomposites, this review is centered on graphene oxide (GO) and reduced graphene oxide (RGO) based polymer nanocomposites and their potential application opportunities in various emerging areas like carbon dioxide (CO2) capture, water purification, photovoltaic cell, sensor, Li-ion batteries, supercapacitors, protective coating, flame retardance composites, electronic devices, automobile body parts, antibacterial coating, biomedical applications (bone and tissue engineering), flexible packaging etc. The aim is to show the full potential of the wonder materials to uplift the standard of living and to judge whether the materials really have the potential to bring future revolution or not.

“…Chitosan is a heterogeneous, linear, cationic and polysaccharide biopolymer with a high molecular weight [6]. The applications of chitosan as an adsorbent in form of flakes are limited by their high crystallinity, low surface area, nonporosity, resistance to mass transfer and low adsorption capacity [7].…”

In the present study, chitosan beads were prepared at different preparation conditions and then applied for adsorption of Reactive Blue 4 (RB4) in a batch adsorption process. Effect of beading parameters such as chitosan concentration, acetic acid concentration and temperature in the removal of RB4 from aqueous solution was investigated. It is found that increasing the concentration of chitosan, acetic acid, and temperature decreased dye removal. The chitosan beads prepared with 2% chitosan and 1% acetic acid concentration at room temperature (30 ± 2 °C) were more suitable for RB4 removal. The beading parameters were found to be effective on the adsorption properties of the prepared adsorbents. Thus, the preparation of chitosan beads at appropriate conditions is a suitable method to improve the anionic dyes adsorption from aqueous solutions.
