Evaluation of Amine Functionalized Thermal Power Plant Solid Waste for Industrial Wastewater Remediation

Figure 7

Adsorption isotherms and nonlinear curve fits of Langmuir (black solid line), Freundlich (blue dash line), and MLF (black dots)) for XO-LCAFA (red circle), XO-LCFA APTES (blue hexagon), MO-LCFA (orange triangle), and MO-LCFA APTES (green diamond), respectively. The error bars show the standard deviation of at least three repeated measurements.
