4-picoline adsorption from aqueous solution by using baggage fly ash (BFA): Parametric, kinetic and thermodynamic aspects

Abstract Numerous harmful characteristics of wastewater containing pyridine chemical have a significant negative impact on human health. Therefore, it is preferred to remove from effluent. The derivatives are 2- and 4-picoline. In this work, an adsorption technique was used 4-picoline the Wastewater treated using natural adsorbent baggage fly ash (BFA). rate 82% reported at pH 6.22, BFA dosage 4 g/L, contact time 6 h. current investigation found that 85.83% could be removed its maximum with temperature 333 K. Investigations were also carried out into how starting concentration affected elimination According kinetic analysis, process uses pseudo-second-order kinetics. thermodynamics study demonstrated all temperatures predicted Freundlich Langmuir equilibrium isotherm models. It further endothermic process.
