(a) How much of the adsorbent is required to recover 90% of the solute from 1000 kg of 10% solution? (b) If 678 kg of the adsorbent is used per 1000 kg of the solution, how much of the Solute is recovered if the treatment is done in two stages, using half of the clay in each stage?

Question
An adsorbent, which is a modified clay, is used to separate an organic compound A from an
aqueous solution. One kilogram of the solution containing 10% of the organic was treated
with varying amounts of the clay in a number of laboratory tests. The following data were
collected. Knowing that Y = 0. 173X1.36, where Y
gram solute per gram solute-free solvent
=
gram solute per gram clay, and X =
Gram clay used
% A in the solution
in equilibrium
