Kinetic and isotherm studies of cr (VI) adsorption from aqueous media by using a synthetic chitosan-allophane nanocomposite

The N2 adsorption–desorption analysis

The N₂ isotherms of prepared allophane, nano chitosan, and allophane-chitosan nanocomposite are indicated in Fig. 1a-c, respectively. The structure properties of compounds, such as surface area, pore…
