The present study was conducted on Ti-MOF and its PVC functionalized composite with the objective of toxic heavy metal ions removal from aqueous media. For achieving this purpose, solvothermal method used to synthesis which then for synthesis. synthesized adsorbent materials were analyzed via different techniques that include FTIR, XRD, SEM EDX analysis along TGA point zero charge (PZC). Batch experiments nickel (Ni) copper (Cu) sorption water, using adsorbents, under experimental conditions like initial concentration, pH, adsorbent's dosage, time contact temperature. by adsorbents increased increasing media dosage concentration. Whereas, pH system, pH-2 pH-10, also enhanced phenomenon, because pronounced forces attraction between positively charged adsorbate negatively surface, accompanied precipitation at a much higher pH. It observed adsorption surface greater than parent MOF material availability number sites, capacity Ni 6.436 29.2 mg/g Cu 21.414 41.616 mg/g. In addition, found have affinity towards as compared ions, is attributed smaller size ions. To determine mechanism, various isotherms examined. results concluded Langmuir isotherm suitable model explain mechanism.Moreover, thermodynamic parameters Gibbs free energy (ΔGo), change in enthalpyΔH, entropyΔS, determined. process be more spontaneous lower temperatures, exothermic nature adsorption, case endothermic ions.Also, negative value ΔS accounts decreased disorderliness system opposite tothat onto Ti-PVC composite.The thus an effective, durable, environmentally friendly adsorbent, wastewater.
