Abstract

One common domestic waste in the waters is detergent residue due to the daily habit of washing clothes. Thus, wastewater treatment is needed to purify the water. One of the methods is photocatalytic degradation. In this study, TiO2 nanoparticles were used to degrade methyl ester sulfonate (MES), one of the raw materials for making detergents. This study aims to investigate the effect of TiO2 concentration, reaction time, and light source on the MES degradation. The variations of the degradation tests included photocatalyst concentrations of 0.5, 1, and 1.5 mg/L, irradiation times of 1, 2, and 3 hours, and UV lamps and sunlight. The residual surfactant in water was analyzed using the Methylene Blue Active Surface (MBAS) method. This study showed that the higher photocatalyst concentration increased the surfactant degradation from 11.97% to 33.91%, and the longer the degradation time, the more surfactant was degraded up to 41.56% after 3 hours. The sunlight source produces 55.72% degradation, more than a 10- watt UV lamp.

Additional Information:

Kandungan limbah yang terdapat di dalam perairan salah satunya disebabkan oleh limbah detergen akibat aktivitas mencuci pakaian. Untuk menanggulangi permasalahan ini dilakukan pengolahan limbah secara fotokatalisis. Pada penelitian ini fotokatalis TiO2 digunakan untuk mendegradasi surfaktan metil ester sulfonat (MES) yang merupakan salah satu bahan utama pembuatan detergen. Penelitian ini bertujuan untuk mengetahui pengaruh konsentrasi TiO2, waktu reaksi, dan sumber sinar terhadap hasil degradasi surfaktan MES. Variasi pengujian yang digunakan meliputi konsentrasi fotokatalis 0,5; 1,0; 1,5 mg/L, lama waktu penyinaran 1; 2; 3 jam, serta sumber cahaya lampu UV dan sinar matahari. Analisis konsentrasi akhir surfaktan menggunakan metode Methylene Blue Active Surface (MBAS). Hasil penelitian menunjukkan bahwa penambahan konsentrasi fotokatalis meningkatkan hasil degradasi dari 11,97% sampai 33,91%. Degradasi surfaktan MES meningkat seiring dengan bertambahnya waktu penyinaran. Setelah dilakukan 3 jam penyinaran didapatkan hasil degradasi sebesar 41,56% oleh sinar lampu UV 10 watt, sedangkan sinar matahari menghasilkan degradasi lebih besar yaitu 55,57%.
