| Summary: | A study to assess the suitability of residual soil as a medium for biodegradation
processes for cyanide is presented in this paper: The residual soils we obtained from
Universiti Kebangsaan Malaysia (UKM) in Bangi (granite residual soil), and Hospital
Universiti Kebangsaan Malaysia (HUKM) in Cheras (sedimentary residual soil). The
cyanide contaminated soils were bio-treated using the slurry phase or leachate
method. Sampels were also mi.xed with a nutrient solution and innoculated with
bacteria that has been breaded in the cyanide contaminated soil. These samples were
tested in two environments, i.e.normal nutrient and catalystic (glucose) nutrient. The
time allowed for the biodegradation processes was 78 hours. Results showed that
HUKM residual soil have.a 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 enhances biodegradation processes |
