Aqueous Adsorptive Removal of Bisphenol A Using Tripartite Magnetic Montmorillonite Composites

The adsorption of bisphenol A into untreated montmorillonite clay, doped titanium composite and cationic polymer modified tripartite magnetic was investigated under different conditions. property the adsorbent ascertained by action external field on materials when dispersed in aqueous media. XRD results for unmodified adsorbents showed that interlayer spacing clay material increases due to intercalation precursor molecules. textural properties from BET analysis pore size specific surface area calculated be 288.08 m2/g while 90.39 m2/g. TGA more stable with lowest percentage mass loss compared montmorillonite. higher capacity. Adsorption best described Freundlich isotherm model, which confirmed process multilayer coverage unto uneven adsorbents. Kinetic treatment data followed a pseudo-second-order kinetic model predominantly chemisorption process. standard Gibb’s free energy computed processes were favourably spontaneous highly negative values −336.70, −533.76 −1438.38 KJ/mol, respectively, montmorillonite, composite. It observed addition aromatic moiety increased pollutant-adsorbent interactions improved capacity micro-pollutants simulated industrial effluent.
