Chromium (VI) adsorption isotherm fitting parameters for chromium (VI) by Cu (I)-MOF in aqueous solution.

Models	Parameters		R^2adj
Langmuir	qm (mg⋅g^−1)	KL (L⋅mg^−1)
	95.92	0.40995	0.9827
Freundlich	KF ((mg⋅g^−1) (L⋅mg^−1) n)	1/n
	37.46	0.2185	0.8279

R²_adj is the adjusted determination coefficient; q_m is the maximum adsorption capacity; K_L is the Langmuir adsorption constant; K_F is the Freundlich adsorption constant; 1/n is the adsorption constant.
