Enhanced Performance of Natural Polymer Coagulants for Dye Removal from Wastewater: Coagulation Kinetics, and Mathematical Modelling Approach

This study explores the potentials of Brachystegia eurycoma coagulant (BEC) and Vigna subterranean (VSC) as natural organic polymers (NOPs) for decolourisation Crystal Ponceau 6R (AR 44) in wastewater. Materials characterisation studies were done on precursors. A detailed kinetics was employed. The procedures evaluated through time-dependent reduction concentration particles, with variation independent parameters. proximate analysis showed protein contents 19.77% 18.15% BEC VSC, respectively. functional test presence –OH, N–H, C=H. surface morphological revealed some rough surfaces, different pores sizes, compact-net structures. order removal efficiency VSC > an optimum 88.8% 73.3%, values coagulation rate constant (K) (α) obtained 6.38 × 10− 4 L mg− 1 min− 1, 1.8 4.03 3 1.9, time, T ag 31.35 26.96 min respectively, disclosed quick coagulation. coagulation-flocculation demonstrated that process conforms to pseudo-second-order model R 2 >0.997, suggesting rate-controlling mechanism is governed by chemisorption. In mass transfer study, experimental data well predicted cross-validation test, a percentage mean relative deviation modulus (M%) 3.26 2.54 These coagulants added meaningful progress wastewater treatment while displaying significant adsorption features. Likewise, usage particle behaviour modelling should be prerequisite water processes.
