> 4. An aqueous solution containing valuable solute is coloured by the presence of small amounts of impurity. It is decolourised using activated carbon adsorbent. The equilibrium relationship is Y = 0.00009xl.7, where X = colour units/kg carbon and Y = colour units/kg solution. If the original solution has 9.8 colour units/kg solution, calculate (i) the amount of colour removed by using 30 kg of adsorbent in a single stage operation and (ii) the amount of carbon needed for a two-stage countercurrent operation if the final colour in the solution is to be 10% of the original value and the solution leaving the first stage has 4 times the final colour of the solution. > 4.
