Abstract
Kajian adsorpsi rhodamin B dengan adsorben zeolit alam hasil aktivasi asam telah dilakukan dengan tujuan untuk mempelajari pengaruh kondisi adsorpsi (pH, waktu kesetimbangan, kecepatan pengocokan dan konsentrasi rhodamin B) terhadap adsorpsi rhodamin B oleh zeolit alam hasil aktivasi asam serta menentukan kondisi optimum adsorpsi. Kondisi aktivasi dilakukan pada 2 gram zeolit alam, menggunakan 50 mL HCl 0,4 M pada lama pengocokan 4 jam dan kecepatan pengocokan 100 rpm. Kondisi adsorpsi dilakukan menggunakan 0,1 gram zeolit alam hasil aktivasi asam dan 25 mL larutan rhodamin B 25 ppm dengan variasi pH 1-13, waktu pengocokan 1, 2, 3, 4, 5 jam, kecepatan pengocokan 100, 125, 150, 175, 200 rpm dan konsentrasi rhodamin B 5, 10, 15, 20, 25, 30, 35, 40 ppm. Konsentrasi sisa rhodamin B ditentukan secara spektrofotometri sinar tampak. Hasil penelitian menunjukkan bahwa kondisi adsorpsi berpengaruh terhadap nilai adsorpsi dengan kondisi optimum dicapai pada pH 2, waktu pengocokan 4 jam, kecepatan pengocokan 150 rpm dan konsentrasi rhodamin B 40 ppm dengan nilai adsorpsi 98,96 ± 0,15% dan kapasitas adsorpsi 9,90 ± 0,02 mg/g.
English Abstract
Study of rhodamine B adsorption with acid activated natural zeolite as an adsorbent has been done to investigate the influence of adsorption conditions (pH, equilibrium time, shaking speed and rhodamine B concentration) toward adsorption of rhodamine B on the acid activated natural zeolite. Another purpose of the study is to determine the optimum condition of the adsorption. Activation was conducted at conditions: 2 grams of the natural zeolite, 50 mL of HCl 0.4 M, shaking speed of 100 rpm for 4 hours. Adsorption was adjusted at conditions: 0.1 gram of the acid activated natural zeolite, 25 mL of rhodamine B solution 25 ppm and various pH (1-13), various shaking period (1, 2, 3, 4, 5 hours), various shaking speed (100, 125, 150, 175, 200 rpm) and various rhodamine B concentration (5, 10, 15, 20, 25, 30, 35, 40 ppm). The remained concentration was analyzed with visible spectrophotometer. The result of the research showed that the adsorption condition influenced the adsorption value within optimum condition at pH 2, equilibrium time of 4 hours, shaking speed of 150 rpm and the rhodamine B concentration of 10 ppm yielding in the adsorption value of 98.96 ± 0.15% and adsorption capacity of 9.90 ± 0.02 mg/g.
