The MW-UIO-66 and MWHAc-UIO-66 sample can reduce the concentration of ,acid chrome blue K, to less than 1 ppm, almost 98% adsorption. It is interesting that the adsorption ability of MW-UIO-66 for ,acid chrome blue K, is better than that of HHAc-UIO-66 even though the surface area of HHAc-UIO-66 (N2, 77 ,K,) is greater than that of MW-UIO-66.
