The Fe ₂ O ₃- TiO ₂ composite is used to adsorb the phosphate pollutant in waste water. The adsorption capacity of Fe ₂ O ₃- TiO ₂ composite for phosphate ions ( = mass of phosphate ion in mg / mass of Fe ₂ O ₃- TiO ₂ composite in g ) from waste water as a function of equilibrium concentration of phosphate ion, i.e. [ PO ₄³⁻ ]_ eq. . at two different pH of waste water at 300 K is shown in the figure below. The isothe
Options
- AValues of k and n at pH 5 are larger than those at pH 9 .
- BValues of k and n at pH 9 are larger than those at pH 5.
- CAt the point P in the plots, the values of k and n for both the pH are same.
- DValue of k is larger for pH 5 while n is larger for pH 9 .
Correct answer
A. Values of k and n at pH 5 are larger than those at pH 9 .
