     Abstract Textile dyeing process is an important source of an environmental pollution. One of the most problems of textile wastewater in addition to both toxic and carcinogenic nature is color effluent. Particularly, alizarin red S (ARS) dye is widely used for dyeing textile materials. The removal of ARS is crucial process from both economical and environmental points of view. This research was aimed to study the adsorption of ARS using graphene oxide (GO) as an adsorbent compared with bare graphite powder (BGP). For optimum conditions, the effects of the initial concentration of ARS, solution pH, adsorbent dosage, and contact time were investigated in detail. The water-soluble dye was analyzed spectrophotometrically at 422 nm. The optimum conditions for ARS removal from aqueous solution were consisted of 350 mg/L initial concentration of ARS dye with 0.02 mg adsorbent at pH 2. The adsorption equilibrium was completely reached within 30 min. The maximum adsorption capacity of GO was 88.50 mg/g which was higher than that of BGP (34.13 mg/g). The adsorption isotherms for GO and BGP fit well with the Langmuir and Freundlich models, respectively. It is, therefore, evident that the as-prepared GO can be used as a high potential adsorbent for the anionic dye.
