Cyanide removal by combined adsorption and biodegradation process

ABSTRACT

Investigation of the effectiveness of simultaneous adsorption and biodegradation [SAB] process over individual processes by using microbes Rhizopus oryzae and Stemphylium loti with granular activated carbon [GAC] as adsorbent was carried out. The maximum removal efficiency of cyanide had been achieved by biodegradation alone was 83% by R. oryzae, while it was 90% by S. loti at initial pH of 5.6 and 7.2 respectively and at initial CN[-] concentration of 150 mg/L. In the combined process efficiency of R. oryzae closer to S. loti [95.3% and 98.6% respectively]
