Abstract
Studi kinetika fotokatalisis zat warna metilen biru oleh seng oksida (ZnO) dilakukan di bawah penyinaran lampu UV-LED. Seng oksida (ZnO) yang digunakan disintesis dengan metode kopresipitasi. Seng oksida (ZnO) dikarakterisasi dengan difraksi sinar-X, FESEM, dan adsorpsi-desorpsi N2. Hasil karakterisasi menunjukkan bahwa seng oksida (ZnO) memiliki struktur kristal heksagonal, ukuran partikel dari 0,125-3 µm, luas permukaan spesifik (SBET), volume pori meso, dan volume pori mikro masing-masing sebesar 60,20 m2/g, 0,541 cm3/g, dan 0,02 cm3/g. Kinetika reaksi fotokatalisis metilen biru mengikuti hukum laju reaksi orde satu. Analisis kinetika Langmuir-Hinshelwood menghasilkan nilai konstanta reaksi fotokatalisis (kr) dan konstanta Langmuir-Hinshelwood masing-masing sebesar 2,2621 L.mg-1.menit-1 dan 0,0144 L.mg-1.

Kinetic study on photocatalytic methylene blue dye by zinc oxide (ZnO) was carried out under UV-LED lamp irradiation. Zinc oxide (ZnO) was prepared by coprecipitation method. Zinc oxide (ZnO) was charaterized by x-ray diffraction, FESEM, and N2 adsorption-desoprtion. Characterization result show that zinc oxide (ZnO) have hexagonal crystal structure, particle size value between 0,125- 3 µm, spesific surface area (SBET), micropore volume, and mesopore volume are 60,20 m2/g, 0,541 cm3/g, and 0,02 cm3/g, respectively. The photocatalytic of methylene blue reaction kinetic follow the first orde rate law. The Langmuir-Hisnhelwood kinetic analysis result shown that photocatalytic reaction constant and Langmuir-Hinshelwood constant value are 2,2621 L.mg-1.minute-1 dan 0,0144 L.mg-1, respectively.
