Abstract

Pada penelitian ini dibuat adsorben silika termodifikasi APTS yang disintesis menggunakan bahan dasar sekam padi. Abu sekam padi ini diolah sedemikian rupa menjadi larutan natrium silikat hingga menghasilkan produk silika gel. Silika gel kemudian dimodifikasi secara kimia dengan reagen 3-aminopropiltrietoksisilan (APTS) sehingga menghasilkan silika termodifikasi APTS. Hasil FTIR menunjukkan bahwa silika termodifikasi APTS mengandung serapan gugus fungsi amino (-NH2), silanol (Si-OH), siloksana (Si-O-Si), dan rantai alifatik (-CH2-). Kandungan dari silika termodifikasi APTS yang ditunjukkan melalui hasil analisis EDX juga menunjukkan bahwa produk memiliki persentase massa masing-masing atom 35.26% silika, 48.47% oksigen, dan 16.27% nitrogen. Hasil penelitian menunjukkan bahwa pH optimum yang diperlukan untuk adsorpsi ion Cu(II) dengan silika termodifikasi APTS adalah 4.0 dan konsentrasi optimum sebesar 100 mg/L. Adsorpsi ion Cu(II) oleh silika termodifikasi APTS mengikuti isoterma adsorpsi Langmuir dengan nilai qmaks sebesar 48.36 mg/g. Dengan demikian adsorpsi terjadi secara kimia dengan membentuk lapisan monolayer. APTS modified silica adsorbent which has been synthesized, using rice hull ash as a raw material. This rice hull ash was carried out to sodium silicate which will be produced to silica gel product. Silica gel was modified with 3-Aminopropyltriethoxysilane (3-APTS) so that produced APTS modified silica. FTIR data indicated APTS modified silica showed the presence of amine (-NH2), silanol (Si-OH), siloxane (Si-O-Si) groups, and aliphatic chains (-CH2-). Contents of APTS modified silica were determined by EDX which had 35.26% silica, 48.47% oxygen, and 16.27% nitrogen. Research results showed that a pH value is 4.0 which is favorable for copper adsorption and optimum concentration value is 100 mg/L Cu(II). Adsorption process of Copper(II) ion by APTS modified silica followed Langmuir isotherm with qmaks 48.36 mg/g. Therefore adsorption happened chemically with monolayer.Key words: APTS modified silica, sol-gel, rice hull ash, adsorption, copper.

Abstract

In this research, silica gel composite modified adsorbents were made with APTES and activated carbon. Silica gel comes from rice husk and activated carbon comes from coconut shell. This rice husk ash is processed in such a way as a sodium silicate solution to produce a silica gel product. The silica gel was then mixed with 3-aminopropylsylatedoxylic reagent (APTES) and activated carbon previously with ZnCl 2 solution and processed into composite. Characterization of composite synthesis using FTIR spectroscopy shows uptake of N-H, silanol (Si-OH), siloxane (Si-O-Si), and C-H bonds. The content of the silica gel composite modified by APTES and activated carbon is indicated through EDX analysis results that the composite of the synthesis has a mass percentage of each atom of 32.92% carbon, 25.88% nitrogen, 26.04% oxygen, and 15.16% silica. The results showed that the optimum pH required for the adsorption of Cd (II) ions with silica gel composite was modified with APTES and the activated carbon was 5.0 and the optimum contact time was 30 minutes. Adsorption of Cd (II) ions by silica gel composites was modified by APTES and activated carbon followed Freundlich adsorption isotherm. Therefore, adsorption occurs forming a heterogeneous monolayer layer. Keywords rice husk ash, silica gel, APTES, activated carbon, composite, adsorption

Abstract

Influence of Nanopaticle CaCO3 Addition to the Physical and Mechanical Properties of Polypropylene-CaCO3 Composite. This research was carried out to study the effect of adding CaCO3 nanoparticle on the physical and mechanical properties of polypropylene-CaCO3 composites. It was characterized by several parameters such as tensile strength, hardness, and thermal analysis including both melting point and heat of fusion using Differential Scanning Calorimetry (DSC). Based on XRD results, the particle size of CaCO3 after 24 hours of milling was 39 nm. There are various compositions of polypropylene-CaCO3 composites (PP MF35: nano-CaCO3) made in this study, namely 40%:60%, 35%:65%, 30%:70%, and 25%:75%. The results showed that the tensile strength of the PP MF35-CaCO3 composites decreased with increasing nano-CaCO3 content. Meanwhile, the hardness of the nanocomposites increased with increasing nano-CaCO3 content, but decreased the melting point and heat of fusions (ΔHm) of the nanocomposites. The infrared spectrum showed that the interaction between PP MF35 and nano-CaCO3 was only physical interaction and there was no chemical reaction.
