DEGRADASI SENYAWA FENOL DENGAN PENAMBAHAN FOTOKATALIS C,N-codoped TiO2

Abstract

Fenol merupakan senyawa organik toksik yang berbahaya bagi kesehatan manusia. Fenol juga terdapat pada limbah seperti limbah rumah sakit, limbah pabrik karet, limbah laboratorium dan lain-lain. Fenol pada konsentrasi tertentu dapat menyebabkan kerusakan hati dan ginjal, melemahkan detak jantung, menurunkan tekanan darah, hingga menyebabkan kematian. Pada penelitian ini, fenol didegradasi secara fotolisis dengan menggunakan lampu UV 10 watt (uap merkuri λ=365 nm) dan lampu sinar tampak (6 Philips LED 13 watt 1400 lux) dengan penambahan katalis C,N- codoped TiO2. Jumlah fenol yang terdegradasi diukur dengan menggunakan spektrofotometer UV-Vis pada rentang 200400 nm. Untuk degradasi 20 mL larutan fenol 8 mg/L didapatkan degradasi fenol sebesar 76,27% (dengan lampu UV) dan 55,08% (dengan lampu sinar tampak). Hasil ini lebih baik dibandingkan dengan tanpa katalis. Dimana kondisi yang sama untuk larutan fenol yang tidak ditambahkan katalis adalah 38,98% (dengan lampu UV) dan 35,59% (dengan lampu sinar tampak). Dari hasil penelitian tersebut dapat disimpulkan bahwa proses degradasi larutan fenol dengan katalis C,Ncodoped TiO2 dengan menggunakan lampu UV (λ=365 nm) memberikan hasil yang baik. Kata Kunci : Degradasi, Fenol, C,N-codoped TiO2
