Table 2 Adsorption characteristics of activated carbon prepared from rice husk
Freundlich isotherm constant \(\ln (q_{e} ) = \ln (k{}_{f}) + \frac{1}{n}\ln (C_{e} )\) | Langmuir isotherm constant \(\frac{1}{{q_{e} }} = \frac{1}{{K_{L} }} + \frac{1}{{K_{L} b}} \times \frac{1}{{C_{e} }}\) | Langmuir–Hinshelwood isotherm constant \(\frac{{C_{e} }}{{q_{e} }} = \frac{1}{{Q_{\hbox{max} } K_{ads} }} + \frac{{C_{e} }}{{Q_{\hbox{max} } }}\) | ||||||
