Adsorption on activated carbon is to be used for reducing phenol concentration in wastewater from 
to 
. The adsorption isotherm at the operating temperature can be expressed as 
; where 
is the phenol concentration in solid (mol/g solid) and 
is the phenol concentration in water (mol/l). The minimum amount of solid (in grams) required per liter of wastewater (up to one decimal place) is 
.
