A Solution of washed raw cane sugar is coloured by the presence of small amounts of an impurity. The solution is to be decolourised by treatment with an adsorptive carbon. The original colour has a colour concentration of 9.6 measured on an arbitrary scale and it is desired to reduce colour to 10 % of its original value. The data for an equilibrium isotherms are as follows: kg carbon/kg solution 0.001 0.004 0.008 | 0.02 0.04 Equilibrium colour, colour units/kg solution 9.6 | 8.6 6.3 4.3 1.7 0.7
