Consider a batch adsorption process, in which $100kg$ of a protein solution of

protein $\frac{?}{kg}$ solution$),$ is contacted with $15kg$ of ion$-$exchange adsorbent. The equilibrium

relationship is given by:

$C_B=\frac{1\mathrm{.}5C_U}{0\mathrm{.}1+C_U}$

Both $C_U$ and $C_B$ are expressed in mass ratio i$.$e$.C_U$ is expressed in $kg$ protein $\frac{?}{kg}$ solution,

and $C_B$ is expressed in $kg$ protein $\frac{?}{kg}$ adsorbent. Determine the equilibrium concentrations

and the fraction of protein adsorbed.
