through sol-gel process and grafting. The sol-gel process was conducted by
reacting of PTMDSr and PTMDSnr with sodium silicate solution at pH of 7.0 to
find HDSSR and HDSSNR, respectively. For grafting technique, commercial

greater than HDSSG (51.323 m

respectively. Adsorption rate constant (k) and adsorption capacity of HDSS for
Mg, Ca, Cu(II), and Cd(II) ions were greater than that of SG at pH 6.0. The
capacity and rate constant (k) of desorption for Mg and Ca ions from HDSS is
higher than that on SG, in both individual and biner system. Generally,
hybridization of sulfonate groups on SG increases the ability of adsorption and
desorption rate of the metal ions investigated.</description><publisher>[Yogyakarta] : Universitas Gadjah Mada</publisher><date>2014</date><type>Thesis:Thesis</type><type>PeerReview:NonPeerReviewed</type><identifier> , CHOIRIL AZMIYAWATI and , Prof. Dr. rer.nat.
