In this research work, the authors investigated the potential of ginger juice as a natural and eco-friendly agent for the decolorization of an azo dye under varying pH conditions. Specifically, the study focused on the probability of dye decolorization at pH 6 and pH 8 to understand the influence of acidic and alkaline environments. Additionally, the effect of hydrogen peroxide (H₂O₂) as a co-treatment agent was assessed. For each pH condition, experiments were conducted both in the presence and absence of H₂O₂ to evaluate its role in enhancing the decolorization process. The decolorization efficiency was quantified by measuring the percentage decolorization based on absorbance values obtained at the dye’s wavelength maximum using a UV-Vis spectrophotometer. The study was carried out over a significant duration of 60 days to ensure a comprehensive evaluation of the dye degradation process. The results showed that at pH 6, the percentage of decolorization was 26.9% in the presence of H₂O₂ and 25.35% in its absence. At pH 8, slightly higher decolorization efficiency was observed, with values of 27.56% in the presence of H₂O₂ and 23.09% in its absence. These findings suggest that ginger juice exhibits potential for dye decolorization, with pH and the presence of hydrogen peroxide influencing the efficiency of the process. These results need more research and may be further optimized for better results with different factors, plant and microbial sources, and use of nutrients etc.
