Abstract
Abstract This research investigated the opportunity to get rid of reactive blue (RB) dye from fabricated wastewater by chemical coagulation, as compared with electro-coagulation. The coagulants used in this study were ferric sulfate Fe2(SO4)3, poly aluminum chloride (PACl), magnesium chloride (MgCl2), and aluminum chloride(AlCl3). Jar test was utilized to determine optimal pH, initial dye concentration, and quantities of dosage coagulants, and then the maximum reactive blue dye removal was acquired. Several test runs were conducted at various conditions (pH, initial dye percentage. potassium chlorideKCl percentage and electrical supply voltage) to assess the removal operation of reactive blue dye using electro-coagulation. The maximum removal effectiveness was 96%, while the optimal coagulant was Fe2(SO4)3 at optimum pH, dosage and dye amount of 6, 300,150 mg/l. In addition to this, the electrochemical cell was fabricated using aluminum plates with dimensions of (8 × 4.5 × 0.3) cm3 as anode and cathode. The outcomes revealed that the ultimate removal was 98%, at an optimal pH of 2, KCl dosage of 1 g/L, initial dye concentration of 80 mg/L, and 25 V at duration time 80 min. The research evidenced the superiority of the electrochemical system for reactive blue removal over the chemical coagulation.
