Nurchabibah, Vera (2018) Penentuan Kapasitas Adsorpsi Karbon Aktif Tempurung Kelapa Terhadap Larutan Hipoklorit. Sarjana thesis, Universitas Brawijaya.
Abstract
Penelitian ini mempelajari pengaruh pH dan pengaruh konsentrasi larutan hipoklorit terhadap adsorpsi hipoklorit menggunakan adsorben karbon aktif tempurung kelapa dengan aktivator NaOH 15% (w/v). Uji pengaruh pH terhadap adsorpsi dilakukan menggunakan 0,1 g adsorben dan larutan hipoklorit 700 mg OCl-/L pada pH 4, 6, 8, 10, 11, dan 12,74 selama 150 menit. Uji pengaruh konsentrasi hipoklorit dilakukan dengan menggunakan 0,1 g adsorben dan larutan hipoklorit pada konsentrasi 200, 300, 500, 700, dan 800 mg OCl-/L selama 150 menit pada pH optimum. Konsentrasi hipoklorit sebelum dan setelah diadsorpsi ditentukan secara volumetri iodometri. Dari hasil penelitian diperoleh pH optimum adalah pH 6 dengan jumlah OCl- yang teradsorpsi sebanyak 54,8%. Pada uji pengaruh konsentrasi hipoklorit, bahwa meningkatnya konsentrasi yang digunakan maka massa yang teradsorpsi juga meningkat, dan kapasitas adsorpsi maksimumnya 400 mg/g.
English Abstract
This research studied the effect of pH and concentration of hypochlorite solution on hypochlorite adsorption using NaOH 15% (w/v) - activated carbon from coconut shell as adsorbent. The effect of pH on adsorption was done using 0.1 g of adsorbent and hypochlorite solution of 700 mg OCl- / L at pH 4, 6, 8, 10, 11, and 12,74 for 150 min. The effect of hypochlorite concentration was performed using 0.1 g of adsorbent and hypochlorite solution at concentrations of 200, 300, 500, 700, and 800 mg OCl- / L for 150 min at optimum pH. Hypochlorite concentrations before and after adsorption were determined by iodometric volumetry. The result showed that the optimum pH was at pH 6 with the adsorbed OCl- amount was 54,8%. Furthermore, increasing the hypochlorite concentration was linear to the increased of the adsorbed mass. The maximum adsorption capacity was 400 mg/g.
