| Summary: | Soil pollution is a widespread problem in developing countries due to uncontrolled
disposal of waste. Thus a study related to soil-pollutant interaction is necessary to
study contaminant behaviour and its migration to surrounding areas. It will also help
to plan necessary mitigation and clean-up measures for contaminated land. One study
which will provide significant input to this cause is the soil- contaminant adsorption
kinetics, as conducted in this research program Two types of soil were used, i.e.
granite residual soil and kaolinite. The adsorption interaction between these two on
cyanide were then compared. Data obtained showed that the granite. residual soil
adsorbed more cyanide than that of kaolinite. The Kd value of 0.64 and 0.022 for
granite residual soils and kaolinite, respectively, obtained from laboratory tests proved
this point. Moreover, other adsorption parameters showed significant differences
between the two soils. This is possibly because the granite residual soil have a higher
organic content and clay fraction than kaolinite. Also the residual soil is less
negatively charged than kaolinite as shown by its more acidic pH. The results also
reveal that residual soils may be an option to kaolinite for use as landfill liners |
