Graphene oxide (GO) with high oxidation degree (OD) and high adsorption capacity was
synthesized easily by modified improved hummer method assisted with ultrasonic at low …

In this study, graphene oxide (GO), produced using the simple Hummer's method, was used
as adsorbent to remove methylene blue (MB) from aqueous solution. Characterizations …

Graphene oxide (GO) was produced from bare graphite (BGP) material and was used as an
intrinsic adsorbent for the removal of malachite green (MG) from aqueous solution. In an …

Graphene was prepared using a modified Hummers' method. The physico-chemical
properties of graphene were characterized by TEM, BET specific surface area, FTIR, Raman …

Graphene oxide (GO) and reduced graphene oxide (rGO) were synthesized from graphite
powder to compare the adsorption capacity of GO and rGO towards a cationic dye …

The adsorption of cationic dyes Basic Yellow 28 (BY28) and Basic Red 46 (BR46) from an
aqueous solution by graphene oxide (GO) as adsorbent is presented. Graphene oxide is …

Graphene oxide was used as efficient adsorbent for the rapid removal of two dyes basic red

Here we prepared three reduced graphene oxides-hydrazine and H2/Ar reduced graphene
oxide at 200 and 500° C (RGO-N, RGO-H-200 and RGO-H-500) with almost identical …

Graphite oxide (GO) was reduced to different reduction degrees by using hydrazine hydrate
and finally to graphene using NH 4 OH. The obtained materials were characterized by X-ray …

Water pollution is a serious environmental problem and coloured pigments are considered
one of the greatest concerning contaminants. Graphene, a new two-dimensional material …
