Abstract (2. Language): 
The optimum parameters (temperature, contact time and adsorbent-to-crude PKO ratio) were determined for the bleaching of PKO using activated snail shell. A D-optimal design for twelve experimental runs at three levels, for temperature, contact time and different amounts (masses) of activated pulverized snail shell (adsorbent-to-crude PKO ratio) was used for the study, and the resulting data fit to a quadratic model. The model adequacy and statistical significance of coefficients were also determined. MATLAB 7.0 was used in the optimization and 3-D plots. The results reveal that the effect of temperature and adsorbent-to-crude PKO ratio were significant and non-linear (quadratic), while time has a non-linear (quadratic) but insignificant effect on the extent of bleaching. The optimum values for temperature, time and adsorbent-to-crude PKO ratio are 187.85OC, 45mins and 2.34: 20 (g/ml) respectively.
