- Abstract
Brilliant green, also known as ethanaminium, is a triarylmethane dye derivative that has been employed as a coloring agent in the textile industry. A sizable volume of vivid green dye was made in a lab while the physio-chemical properties were investigated. This study looked at how to extract the brilliant green dye from the aqueous reagent using the coagulation-flocculation method to provide the desired features. Used as a flocculant and coagulant, respectively, polyaluminum chloride (PAC). Sodium bisulfate (NaHSO4) solution and hydrochloric acid (HCl) employed to alter the pH during the treatment process. Different pH values and coagulant and flocculant dosages used in a series of jar tests. The supernatant aqueous effluent determined by numerous experimental studies termed turbidity, chemical oxygen demand (COD), colour, and suspended solids (SS) after every experimental analysis and after the practical investigation. The effectiveness of the treatment ranged from a turbidity reduction of 40%-98% to the elimination of 15%-99.2% of COD and a range of 20%-97.3% of suspended particles. In order to optimize removal efficiency, the optimal parameters for the entire quadratic model found using the analysis of variance (ANOVA). By using SEM, XRD, and FTIR analyses, the surface morphology of the sludge characterized. The treatment of brilliant green dye in aqueous solution identified as the successful solution by this coagulation-flocculation procedure using jar test equipment.
