Summarized kinetic parameters for the grafted and ungrafted samples.

Pseudo First Order			Pseudo Second Order			Elovich			Intraparticle Diffusion
Parameters	Ungrafted	Grafted		Ungrafted	Grafted		Ungrafted	Grafted		Ungrafted	Grafted
qe (mg/g)	121	530	qe (mg/g)	127.982	954.645	β (mg/g/min)	0.043	0.005
k1 (1/min)	0.035	0.040	k2	1.07 × 10−3	1.5× 10−5	α (mg/g/min)	47.903	32.722	K	13.808	54.074
R2	0.967	0.992	R2	0.973	0.95	R2	0.9	0.958	R2	0.675	0.9217

Where: α (mg/g/ min) and β (mg/g/min) are Elovich constants; R² is the regression coefficient.
