Pb(II) adsorption from aqueous solution onto nanoparticle MCM-41 amine-functionalized

a novel nano hybrid adsorbent MCM-41/N-(3-trimethoxysilyl)-propyl)diethylenetriamine (MCM-41/TMSPDETA) was prepared via co-condensation method and characterized using DLS (Dynamic Light Scattering)and Fourier Transform Infrared (FTIR) analysis. The nano hybrid adsorbent was applied in batch experiments underdifferent controlling factors by varing contact time, initial concentration of Lead (Pb(II)) ion and adsorbent dose. TheLangmuir, the Freundlich and Dubbinin-Radushkevich isotherms have been used to the experimental data. The adsorptiondata were well described by the Langmuir isotherm and maximum capacity of the nano adsorbent was obtained to be58.823 and 20.921 mg g−1 for Pb (II) and Ni (II) ions for an intial concentration range 10-70 mgL-1.
