Abstract

Optimation of cyanide adsorption has been done from tapioca industry liquid waste using activated sludge. This study was aimed to know the optimum condition of the adsorption process and to determine the adsorption efficiency of active sludge to cyanide contents of tapioca industry liquid waste. The roommate’s sludge was dried, and activated using 3M HCl and calcinated at temperatures of 800oC. The optimum condition was determined using adsorption time variations at 7, 8, 9 and 10 hours and adsorbent weight variation of 150 mg, 200 mg, 250 mg, and 300 mg. This optimum condition determination was done to 50 mL of simulated waste. The optimum condition results of adsorption time were 8 hours, adsorbent weight was 250 mg, and adsorption efficiency was 85.36%. The optimum condition refers to tapioca industry liquid waste. Cyanide content before adsorption was 8.32 ppm and after adsorption was 1.22 ppm, its adsorption efficiency was 85.30%. This result has not fulfilled the requirement according to KEP-51 / MENLH / 10/1995 yet, about “Liquid Waste Quality Standards For Tapioca Industry” which states that the maximum cyanide content is 0.5 ppm.
