“…Kinetics measurements were made by preparing three sets of reaction mixtures in which one species was varied while the others were kept constant at a given concentration. All contents were mixed, and the progress of the (inlets) reaction was monitored by recording the change in optical density max λ during the reaction on a UV/Visible spectrophotometer (Shimadzu 160-A).The reaction order was evaluated by measuring the specific reaction rate at various pH [19][20][21][22][23][24][25][26][27]. The percent decrease in absorbance was calculated by using the formula:…”

This study aimed to explore the oxidation kinetics of reactive Drimaren Blue-HFRL (DB-HFRL), leading to its degradation by permanganate ions under diverse pH conditions at λ max 610nm using a spectrophotometer. The oxidation reaction of DB-HFRL was observed on several parameters in acidic and alkaline solutions, such as dye and potassium permanganate (KMnO 4 ) dosage, pH, reaction time, and temperature. The oxidative products were analyzed through IR spectroscopy, followed by the determination of chemical oxygen demand (COD) and biological oxygen demand(BOD) of reaction mixtures. The change in pH on the oxidation capability of KMnO 4 was monitored under mono, di, and tri protic acids and an alkaline medium. Results showed that oxidation leading to degradation was higher at low pH compared to higher pH. The percent decolorization/ oxidation of dye waste effluent was rapid at higher concentrations of KMnO 4 in the presence of different acids such as CH 3 COOH, H 2 SO 4, and H 3 PO 4 (76.19%) while minimum in alkaline medium (17.19%). It was observed that the dye decolorization rate was directly proportional to the hydrogen ion concentration in a given acidic medium (tri-protic acid, H 3 PO 4 ). This indicates that H ions are significant in dye colour removal and renovation of wastewater. COD of the laboratory scale prepared wastewater (4500mg/L) showed the effectiveness of the developed process where a remarkable decline in chemical oxygen demand (COD) was observed in an acidic medium. This study establishes a cost-effective method to treat textile effluent to protect the ecosystem.

“…Due to the complex aromatic structures, these dyes are unaffected by light, temperature and microbial attack. Because of this, they are known as recalcitrant compounds [24,25]. The dye sewages are high in colour, pH, chemical oxygen demand (COD), and biological oxygen demand (BOD) [26][27][28][29][30][31][32][33][34].…”
