Ever-increasing demands of dye and printing technology has resulted in uncontrolled disposal of dyes into water bodies leading to tremendous environmental pollution. Methylene blue (MB), a popular, water soluble blue dye, has been reported as a major component of water pollutant. It is carcinogenic as well as has enormous toxic effects on the aquatic organisms, thereby considerably affecting ecological food chain. The removal of these types of dyes from water is thus, an important issue and consequently modern technology strongly recommend for less expensive, facile techniques in this regard. Graphene oxide (GO), oxidized form of graphene containing oxygen functionalities, is found to exhibit superior adsorption property compared to available carbon-based materials and therefore possesses significant roles in waste water treatment technology. This overview categorically narrates recent progresses on the fabrication, performances and achievements of GO as adsorbent with a first-hand idea of plausible mechanism of adsorption of MB. A concise outline on the challenges and future prospects of this field has also been highlighted.
