Adsorption of Pb(II) onto KCC-1 from aqueous solution: Isotherm and kinetic study

In this study, the removal of Pb(II) from aqueous solution using KCC-1 was investigated. BET and TEM revealed the favourable structure of KCC-1 which consists of fibrous morphology and high surface area. Batch adsorption experiment were performed to study the effect of contact time (40 – 160 min), e...
