$12\mathrm{.}2-1.$ Batch Adsorption for Phenol Solution. A wastewater solution having a volume of $2\mathrm{.}5m^3$ contains $0\mathrm{.}25kg$ phenol$/m^3$ of solution. This solution is mixed

thoroughly in a batch process with $3\mathrm{.}0kg$ of granular activated carbon until

equilibrium is reached. Use the isotherm from Example $12\mathrm{.}2-1($q$=0\mathrm{.}199$c$^(0\mathrm{.}229))$ and calculate

the final equilibrium values and the percent phenol extracted.
