Refianti, Vista Agnesia (2018) Pengaruh Konsentrasi NaOH Pada Aktivasi Arang Tempurung Kelapa Untuk Adsorpsi Hipoklorit. Sarjana thesis, Universitas Brawijaya.
Abstract
Penelitian ini bertujuan untuk mengetahui pengaruh konsentrasi NaOH sebagai aktivator arang tempurung kelapa terhadap adsorpsi hipoklorit, dan mengetahui pengaruh waktu kontak terhadap adsorpsi hipoklorit menggunakan karbon aktif teraktivasi NaOH. Arang diperoleh dari hasil pemanasan tempurung kelapa menggunakan tanur 6000C dan diperoleh rendemen arang sebesar 19,68% (w/w). Karakterisasi adsorben karbon aktif dilakukan menggunakan FT-IR dan SEM. NaOH sebagai aktivator divariasi pada konsentrasi 0, 5, 10, 15, dan 20%w/v. Adsorpsi hipoklorit dilakukan pada berbagai waktu kontak 30, 60, 120, 150, dan 180 menit dengan menggunakan 0,1 g adsorben dan 100 mL larutan hipoklorit 300 mg/L. Konsentrasi hipoklorit sebelum dan setelah adsorpsi ditentukan secara titrasi iodometri. Hasil penelitian menunjukkan bahwa arang tempurung kelapa yang diaktivasi dengan NaOH 15% mengadsorpsi hipoklorit secara optimal. Waktu kesetimbangan adsorpsi dicapai pada menit ke 60.
English Abstract
The aims of the research were to investigate the effect of NaOH concentration as coconut shell charcoal activator toward hypochlorite adsorption, and the effect of contact time toward hypochlorite adsorption with NaOH-activated carbon. Charcoal was obtained from heating the coconut shell in a furnace at 6000C with the yield of 19.68% (w/w). Activated carbon was characterized by FT-IR and SEM. NaOH as an activator was varied at concentration 0, 5, 10, 15, and 20% (w/v). Hypochlorite adsorption was conducted at various contact times of 30, 60, 120, 150, and 180 minutes by using 0.1 g of adsorbent and 100 mL of hypochlorite solution 300 mg/L. Hypochlorite concentrations before and after adsorption were determined with iodometric titration. Result showed that coconut shell charcoal activated with 15% (w/v) NaOH optimally adsorbed hypochlorite solution. Equilibrium adsorption was reached at 60 minutes.
