Abstract

Telah dilakukan desain sel elektrolisis tanpa membran menggunakan elektrolit larutan garam untuk memproduksi anolyte murni sebagai disinfektan. Anolyte dipilih karena merupakan disinfektan yang efikasinya baik namun tetap aman dan ramah lingkungan. Dilakukan percobaan berupa elektrolisis batch 1 untuk mengetahui retention time tiap variasi volume dan batch 2 untuk mengetahui pH pada 4 titik di dalam sel. Hasil yang didapatkan pada elektrolisis batch 1 adalah pada volume 2, 4, 5, 6 liter memiliki retention time sebesar 10, 25, 30, dan 45 menit untuk mencapai pH yang diinginkan (6-6,5). Hasil dari elektrolisis batch 2 mendapatkan bahwa variasi pH di 4 titik yang dipilih cukup presisi dan akurat pada volume 2, 4 , dan 5 liter. Setelah itu diambil sampel berupa endapan di dasar sel untuk karakterisasi XRD, dan sampel berupa larutan di titik antara anoda dan katoda untuk uji titrasi balik. Karakterisasi XRD menunjukkan bahwa terbentuk beberapa komponen lain didasar sel. Sementara hasil titrasi menunjukkan bahwa pada larutan mengandung 0,001 M NaOH. Pengujian antibakteri juga dilakukan untuk mengetahui efikasi larutan terhadap bakteri E. Coli dan S. Aureus. Hasil pengujian menunjukkan bahwa larutan memiliki efikasi yang cukup baik untuk menghambat pertumbuhan 2 bakteri tersebut. ====================================================================================================== A membraneless electrolysis cell has been designed using a salt solution electrolyte to produce pure anolyte as a disinfectant. Anolyte was chosen because it is a disinfectant with good efficacy but still safe and environmentally friendly. An experiment was conducted in the form of electrolysis of batch 1 to determine the retention time of each volume variation and batch 2 to determine the pH at 4 points in the cell. The results obtained in batch 1 electrolysis are volumes 2, 4, 5, 6 liters have retention times of 10, 25, 30, and 45 minutes to reach the desired pH (6-6.5). The results of batch 2 electrolysis showed that the pH variations at the 4 selected points were quite precise and accurate at volumes of 2, 4, and 5 liters. After that, a sample is taken in the form of a precipitate at the bottom of the cell for XRD characterization, and a sample is a solution at the point between the anode and cathode for the back titration test. XRD characterization showed that several other components were formed in the cell base. While the titration results show that the solution contains 0.001 M NaOH. Antibacterial testing was also carried out to determine the efficacy of the solution against E. Coli and S. Aureus bacteria. The test results showed that the solution had good enough efficacy to inhibit the growth of these 2 bacteria.
