These synthetic powders, natural pyrophyllite and their 3-mercaptoprophyltrimethoxysilane coated forms were utilised as adsorbents for the removal of Cu(II) ions from aqueous solutions. The adsorption increased when natural and synthetic powders coated with SH-Si were used. It was concluded that the dried powders obtained from the hydrolysis-condensation product of Al(OBus)(3) and its alcohol modified form, and coated pyrophyllite would substitute for Amberlite IR 120 Na form resin.eninfo:eu-repo/semantics/closedAccesspyrophyllitealuminium oxidecoatingmercapto silaneadsorbentcopper(II)Conference Object264-2682239224210.4028/www.scientific.net/KEM.264-268.22392-s2.0-8644283746Q4WOS:000223059700537N/A
