description: Abstrak    Sintesis material hibrida amino silika (HAS) dan hibrida merkapto silika (HMS)  tercetak ion Pb(II) (HAS-t-Pb(II) dan HMS-t-Pb(II)) telah dilakukan  menggunakan senyawa aktif 3-aminopropiltrimetoksisilan (3-APTMS) dan 3-  merkaptopropiltrimetoksisilan (3-MPTMS) dengan prekursor tetraetilortosilikat  (TEOS). Karakterisasi material hasil sintesis tersebut menggunakan  spektrofotometer inframerah (IR) dan Scanning Electron Microscope- Energy  Dispersive X-Ray Spectrometer (SEM-EDX). Kadar ion logam dianalisis  menggunakan spektrofotometer serapan atom (SSA). Perbandingan kemampuan  adsorpsi material HAS dengan HAS-t-Pb(II) dan HMS dengan HMS-t-Pb(II)  dilakukan melalui uji adsorpsi yang meliputi laju, kapasitas dan selektivitas  adsorpsi terhadap ion logam Pb(II). Laju adsorpsi ditentukan menggunakan  kinetika pseudo orde dua dengan nilai konstanta laju (k2) untuk HAS-t-Pb(II) dan  HMS-t-Pb(II) masing-masing 1,07 dan 33,30 g mmol-1 menit-1. Kapasitas  adsorpsi material HAS-t-Pb(II) dan HMS-t-Pb(II) mengikuti persamaan isoterm  Langmuir dengan nilai masing-masing 15,15 dan 29,41 mol g-1. Material HAS-tPb(II) dan HMS-t-Pb(II) lebih selektif terhadap ion Pb(II) dibandingkan Zn(II),  Ni(II) dan Cd(II) dengan koefisien selektivitas (α) > 1. Selektivitas material HASt-Pb(II) dan HMS-t-Pb(II) masing-masing meningkat hingga 2,41 dan 3,58 kali  lebih selektif terhadap ion Pb(II) dibandingkan material HAS dan HMS.  Kata Kunci : Hibrida Amino Silika, Hibrida Merkapto Silika, Adsorpsi selektif                      Abstract    The synthesis of material amino silica hybrid (HAS) and merkapto silica hybrid  (HMS) imprinted ions Pb(II) (HAS-t-Pb(II)) and (HMS-t-Pb(II)) has been conducted  using a compound of active 3-aminopropiltrimetoksisilan (3-APTMS) and 3-  merkaptopropiltrimetoksisilan (3-MPTMS) with the precursor of the  tetraetilortosilikat (TEOS). Characterization result of materials synthesis using  spectrophotometer infrared (IR) and Scanning Electron Microscope- Energy  Dispersive X-Ray Spectrometer (SEM-EDX). The levels of metal ions are analyzed  using atomic absorption spectrophotometer (AAS). Comparison of ability of  adsorption material HAS with HAS-t-Pb(II) and HMS with HMS-t-Pb(II) done via a  test that includes a rate, adsorption capacity and selectivity adsorption of metal ions,  Pb(II). The rate of adsorption is determined using the pseudo first order kinetics with  two rate constants (k2) to HAS-t-Pb(II) and HMS-t-Pb(II) each 1,07 and 33,30 g  mmol-1 min-1. Adsorption capacity of the material HAS-t-Pb (II) and HMS-t-Pb(II)  follow the Langmuir equation isoterm with each value 15,15 and 29,41 mol g-1. The  Material HAS-t-Pb(II) and HMS-t-Pb(II) more selective of Pb(II) ions than Zn(II),  Ni(II) and Cd(II) with selectivity coefficient (α)> 1. Selectivity material HAS-tPb(II) and HMS-t-Pb (II) each rising to 2,41 and 3,58 times more selective for the  Pb(II) ions compared HAS and HMS material.
