Abstract

A study to analyse the suitability of residual soil as a medium for biodegradation processes for cyanide Is presented In this paper. The analysed residual soils were obtained from Universiti Kebangsaan Malaysia (UKM) in Bangi (sedimentary residual soil), and Hospital Universiti Kebangsaan Malaysia (HUKM) In Cheras (granite residual soil). Both sites are in the state of Selangor, Malaysia near Kuala Lumpur, the capital city of Malaysia. The cyanide-contaminated soils were bio-treated using the slurry phase or leachate method. Samples were also mixed with a nutrient solution and inoculated with bacteria that have been previously bred in the cyanide-contaminated soil. These samples were tested in two environments, i.e. normal nutrient and catalytic (glucose) nutrient. The time allowed for the biodegradation processes was 78. The results showed that in both residual soil samples, the concentration of cyanide decreased, while the blomass of bacteria Increased. All results showed that HUKM residual soil has better characteristics for biodegradation processes compared to UKM residual soil. This is due to greater organic carbon, organic content and acidity of the HUKM residual soil that enhance biodegradation processes.
