In this work, FeOOH-Cellulose-TiO2 hybrid nanocomposite was prepared via formaldehyde crosslinker and used for lead ions, Pb(II), remediation from water. Adsorption of Pb(II) from the water done by using batch and microwave adsorption approaches. According to this work, the microwave adsorption technique showed the best adsorption efficiency. The extraction of lead (II) under microwave irradiation was accomplished via controlled parameters (pH 7 with short contact time 20 sec) and the maximum metal capacity value (9600 mu mol.g(-1)) obtained by using 5 mg of FeOOH-Cellulose-TiO2 nanocomposite. Kinetic model and adsorption isotherm study revealed the best fitting with Lagergren-second-order and D-R model, respectively. The efficiency of FeOOH-Cellulose-TiO2 nanocomposite for removal of Pb(II) from tap water and wastewater was configured by using column technique and microwave technique. The highest percent removal values of Pb(II) from tap and wastewater samples were 98% and 99%, respectively.
