    Abstract

    ABSTRACT Muhammad Yuniyanto, 2006, STUDY PERFORMANCE OF OPTODE Zn(II) AND Cr(III) IONS WITHOUT PLASTICISER FROM AMINOPROPYLTRIMETHOXYSILANE AND OCTYLTRIETHOXYSILANE WITH CHROMOIONOPHORE 4-(2-PIRIDILAZO)RESORCINOL. Thesis. Department of Chemistry. Mathematics and Science Faculty. Sebelas Maret University The synthesis of new optode from APTS-OTES matrix was successfully made by adding chromoionophore PAR (4-(2-piridilazo)resorcinol). The APTS- OTES matrix, a compiler optode materials, was synthesised from OTES (octyltriethoxysilane) and APTS (aminopropyltrimethoxysilane) with sol-gel method using base-catalyzed NH4OH 0,05 M. APTS-OTES matrix has a good thermal resistance since there was not any change in polimeric structure at 206,320 C and glass transition (Tg) at 315,530 C. The SEM photo shows that there not any cracking on surface APTS- OTES matrix. Physically, matrix was showed to be transparent and from spectrophotometer Uv-Vis shows not any absorbtion at visible region, therefore it was useful to become matrix for optode. Optode was made by dipping the APTS-OTES matrix to PAR solution 10-4 M. PAR is good as chromoionophore, because it has ε: 3,27x104 L.mol -1 .cm-1 . The adding of PAR could shifted λmaks of APTS-OTES matrix 303,00 nm became 405,80 nm. The result studied PAR-metals complex in aqueous with 1:1 stoichiometry with metal ions showed that complex Zn(II)-PAR had a good optic properties, because complex Δλ Zn(II)-PAR is higher than complex Cr(III)-PAR. Optode was applicated for optic sensor of Zn(II) and Cr(III) ions. The result of extraction constant (Keks) optode to ion Zn(II) is 0,40 and ion Cr(III) is 0,21. Optode also could be regenerated by using HCl 1M .
