NOVELTY - Nanocolloids composition, comprises 20-40 wt.% graphene oxide and 50-70 wt.% glycerol. USE - Nanocolloids composition, used for reduction of graphene oxide and waste water treatment (claimed). ADVANTAGE - The composition is non-toxic, capable of photo-catalytically degrade organic dyes present in waste water and is highly stable for reduction of graphene oxide, as well capable of waste water treatment. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing composition, which involves: dispersing varying amount of GO in glycerol to obtain a mixture and sonicating mixture for up to 1 hours at room temperature 30℃, followed by resting sonicated mixture at 30℃ for 24 hrs to achieve thermal equilibrium in order to obtain nano colloid composition.
