Q8. An aq. Sol4; containing of valuable solcte is coloured by small amount of an impurity. Before crystalization the impusity is to be removed by adsoption on a decolouring carbon. Which adsobs only insignificant amount of principle solute. A series of laboratory test was made by stioning varios amount of the adsorbent into batches of the original sol n, until equilibrium was established, using following data at const. tempr. The colour imtensity was mealured on an arbitan, scale prepontional to the conch of Coloured substans TI is desired to reduce the colvor +010% of its unginal value 9.6. Detemine the quantity of Frech carbon requime per 1000kg of soln for a eingle stage operation, for a two stage cross currem process lising the minm total amount of carbon \& for a two ctage corenter current operot
