Wahyuningsih, Suharni (2008) Studi Adsorpsi Karbon Aktif Sintetik Terhadap Rhodamin B. Sarjana thesis, Universitas Brawijaya.
Abstract
Telah dikaji tentang adsorpsi karbon aktif sintetik terhadap rhodamin B. Penelitian ini bertujuan untuk menentukan lama dan kecepatan pengocokan optimum pada proses adsorpsi oleh karbon aktif sintetik terhadap rhodamin B serta mempelajari perbedaan nilai adsorpsi karbon aktif sintetik terhadap karbon aktif perdagangan. Adsorpsi dilakukan dengan kondisi : 0,1000 g karbon aktif, 25 mL larutan rhodamin B 100 ppm (pH 9) dengan berbagai lama pengocokan yaitu 1, 2, 3, 4, 5 dan 6 jam serta kecepatan pengocokan yaitu 100, 125, 150, 175 dan 200 rpm. Penentuan konsentrasi sisa rhodamin B dilakukan dengan menggunakan metode spektrofotometri. Dari hasil penelitian diperoleh bahwa lama dan kecepatan pengocokan optimum pada proses adsorpsi oleh karbon aktif sintetik terhadap rhodamin B diperoleh pada lama pengocokan 3 jam dan kecepatan pengocokan 150 rpm dengan nilai adsorpsi sebesar 99,28±0,00% untuk konsentrasi rhodamin B 100 ppm. Nilai adsorpsi karbon aktif sintetik relatif sama dengan karbon aktif perdagangan (0,99 kali nilai adsorpsi karbon aktif perdagangan).
English Abstract
The study adsorption of synthetic active carbon to rhodamine B was studied. The research target is to determined optimum shaking time and speed in adsorption process by synthetic active carbon and to study the different adsorption performance of the synthetic active carbon with the commercially active carbon. The adsorptions were conducted at condition of 0.1000 g active carbon , 100 mL of rhodamine B solution 100 ppm (pH 9), various shaking time (1, 2, 3, 4, 5, and 6 hours) and various stirring speed (100, 125, 150, 175, and 200 rpm). Remain rhodamine B was determined with spectrophotometry method. Result of the research showed that the optimum shaking time and speed on adsorption process by synthetic active carbon to rhodamine B obtained at 3 hours and speed at 150 rpm with value adsorption 99.28±0,00% for concentration rhodamin B 100 ppm. This value of the synthetic active carbon relative with value of the commercially active carbon (0.99 times the value of commercial active carbon).
