| dc.description.abstract | WILDA NA MORA SIREGAR. Sintesis Fotokatalis Komposit Zeolit
Alam-TiO2/ZnO/CuO untuk Fotodegradasi Zat Warna Biru Metilena. Dibimbing
oleh KOMAR SUTRIAH dan SRI MULIJANI.
Industri tekstil menghasilkan limbah cair yang mengandung zat warna
sintetik, salah satunya biru metilena yang bersifat karsinogenik, mutagenik, dan
sukar terdegradasi secara alami, tetapi dapat diatasi melalui fotodegradasi
menggunakan fotokatalis. Penelitian ini bertujuan mengevaluasi kesesuaian rasio
optimum zeolit alam-TiO2/ZnO pada sistem zeolit alam-TiO2/ZnO/CuO
(ZA-TZC), menentukan komposisi terbaik, dan mengkarakterisasi material serta
kinetika reaksinya. Fotokatalis disintesis menggunakan metode kopresipitasi dan
impregnasi dengan berbagai variasi rasio. Data fotodegradasi dianalisis
menggunakan ANOVA dua arah dengan replikasi. Rasio ZA:TZC (75:25)
terkonfirmasi sebagai komposisi terbaik dengan persen degradasi tertinggi sebesar
92,42% di bawah sinar UV 18 W dan sinar tampak 10 W. Hasil ANOVA
membuktikan bahwa penyinaran dan komposisi fotokatalis memberikan pengaruh
yang signifikan terhadap persen degradasi. Karakterisasi XRD menunjukkan
keberhasilan sintesis. Kinetika reaksi fotodegradasi mengikuti model orde pertama.
Komposit ZA:TZC (75:25) berpotensi dikembangkan sebagai fotokatalis untuk
pengolahan limbah cair yang mengandung zat warna biru metilena. | |
| dc.description.abstract | WILDA NA MORA SIREGAR. Synthesis of Natural Zeolite Composite
Photocatalyst-TiO2/ZnO/CuO for Photodegradation of Methylene Blue Dye.
Supervised by KOMAR SUTRIAH and SRI MULIJANI.
The textile industry produces liquid waste containing synthetic dyes, one of
which is methylene blue, which is carcinogenic, mutagenic and resistant to natural
degradation but can be overcome through photodegradation using a photocatalyst.
This research aims to evaluate the suitability of the optimum ratio of natural
zeolite-TiO2/ZnO when applied to the natural zeolite-TiO2/ZnO/CuO (ZA-TZC)
system, to determine the best composition, and to characterize the material and its
reaction kinetics. The photocatalyst was synthesized using coprecipitation and
impregnation methods with various ratios. Photodegradation data were analyzed
using two way ANOVA with replication. The ZA:TZC ratio of 75:25 was
confirmed as the best composition with the highest degradation percentage of
92,42% under 18 W UV and 10 W visible light irradiation. ANOVA results proved
that irradiation and photocatalyst composition had a significant effect on the
degradation percentage. XRD characterization confirmed the success of the
synthesis. The photodegradation reaction kinetics followed a first-order model. The
ZA:TZC (75:25) composite has the potential to be developed as a photocatalyst for
the treatment of liquid waste containing methylene blue dye. | |
