In this study, hybrid beads were prepared using tannin and chitosan. Batch experiments were carried out to remove Pb(II) from aqueous solution using hybrid bead. According to the FT-IR analysis, the hybrid beads had carboxylic, carbonyl groups, carboxylic acids, and bonded-OH groups, which made it very easy to adsorb heavy metals. The adsorption of Pb(II) using hybrid beads was suitable for pseudo-second-order and Langmuir isotherms. The maximum adsorption capacity of Langmuir was 123.19 mg/g of Pb(II). The adsorption strength of Pb(II) to the hybrid bead was high and showed the isothermal adsorption characteristics of L type. In the thermodynamic experiment, ΔGo shows a negative value, and ΔHo and ΔSo show a positive value. It can be seen that the adsorption process of Pb(II) using hybrid bead is a spontaneous endothermic reaction and the affinity between adsorbent and adsorbate is very good. Hybrid beads can efficiently adsorb and remove Pb(II) as an inexpensive and environmentally friendly adsorbent.
