Abstract: The pyrophyllite used in this study was from Taishun County(Wenzhou,China). The surface of pyrophyllite was modified by coating with N-(n-butyl)-3-aminopropyltrimethoxysilane (BAPTS) coupling agent and utility of the BAPTS-modified pyrophyllite was investigated as an adsorbent for removal of Pb(II) ions from aqueous solutions. XRD and SEM analysis were used to characterise the surface modification. It can be clearly observed that the pyrophyllite looses its aculeated surface structure and gains more smooth morphology. It was observed that the BAPTS -modified pyrophyllite adsorbed approximately 94.50% of Pb(II) ions at an initial concentration of 10 mg/l and an amount of BAPTS of 2.0%.
