Abstract

This study aims to determine the effect of the use of TiO2/Zeolite on reducing concentrations of nitrate, nitrite, ammonia, phosphate, BOD, COD and pH in agricultural wastewater by photolysis. In this study, sample analysis was carried out using UV-Vis spectrophotometer and FTIR and for the characterization of TiO2/Zeolite catalysts using FTIR, XRD and SEM. In agricultural wastewater samples, the initial concentration of nitrate was 11,409 mg/L, nitrite was 0,424 mg/L, ammonia was 5,075 mg/L and phosphate was 5,364 mg/L. The most optimum decrease in concentration for nitrate, nitrite, ammonia and phosphate, respectively, was 4,332 mg/L with an irradiation time of 90 minutes; 0,118 mg/L with an irradiation time of 75 minutes; 0.395 mg/L with an irradiation time of 90 minutes and 1,207 mg/L with an irradiation time of 60 minutes on the addition of TiO2/Zeolite as much as 0.8 grams for the determination of nitrate and phosphate while for nitrite and ammonia as much as 0.6 grams. Prior to the degradation, the BOD value was 62,4 mg/L and the COD value was 107,07 mg/L. Meanwhile, after degradation, the BOD value decreased to 5,92 mg/L and COD to 35 mg/L. The results of the analysis using FTIR on agricultural wastewater show that there is no significant shift in wave number before and after degradation. The characterization of TiO2/Zeolite catalyst using FTIR, XRD and SEM did not show significant changes before and after the degradation process was carried out which indicated that TiO2/zeolite could be applied in degrading agricultural wastewater.

Abstract

Penelitian ini bertujuan untuk mensintesis Ceria berpori yang telah menarik banyak minat dalam aplikasinya di bidang katalisis karena memiliki siklus redoks yang unik (Ce3+/Ce4+), luas permukaan yang besar, ukuran pori teratur, dan difusi yang selektif dalam pori-pori. Struktur berpori Ceria dapat disintesis melalui proses protecting etching dengan kombinasi CTAB dan PVA sebagai protecting agent. Dibandingkan dengan penelitian sebelumnya yang terbatas dan hanya dilakukan pada logam silika, metode ini memiliki beberapa keunggulanya itu kompatibilitas untuk oksida logam yang berbeda khususnya logam transisi, reaksi satu pot tanpa prosedur multi-langkah, sintesis cepat (10 menit) dalam proses etching hingga membentuk produk berpori. Hasil analisis morfologi permukaan dengan SEM menunjukkan bahwa Ceria hasil sintesis dengan menggunakan CTAB sebagai templating agent memiliki permukaan yang berpori dan bentuk yang mengarah seperti batang (rod) serta memiliki ukuran partikel yang lebih kecil dibandingkan Ceria hasil sintesis tanpa CTAB sebagai templating agent. Hal tersebut membuktikan bahwa kombinasi CTAB sebagai templating agent dan PVA sebagai protecting agent selama proses etching dapat mengopatimalkan pembentukan struktur berpori pada Ceria sehingga dapat berpotensi iuntuk aplikasi katalitiknya.
