Abstract:

In view of the water pollution caused by printing and dyeing wastewater, a three dimensional porous Zr-organic skeleton material with high water stability was successfully assembled from ZrCl4 with 2,2'-Biquinoline-4,4'-dicarboxylicacid (H2L) under 100 ℃ with solvothermal synthesis method. It was deployed to realize the selective and recyclable adsorption of dyes with different sizes from water. The results demonstrate that the selective adsorption towards Methylene Blue (MB), Cationic Brilliant Red 5GN (BR14) and Cationic Bright Yellow 7GL (BY24) is achieved in 6 groups of mixed aqueous solution composed of reactive dyes and cationic dyes. The removal efficiency towards cationic dyes are all above 79%, in which the removal efficiency for MB is as high as 99.78%. After 8 rounds of adsorption-desorption cycle experiment, the adsorption efficiency of 40 mL 15.7 mg/L MB is still up to 97.0%. In addition, X-ray powder diffraction measurements shows that the crystallinity of Zr-MOF is almost unchanged after 8 adsorption-desorption cycles and 48 h in strong acid (hydrochloric acid) and strong alkali (NaOH) aqueous solution with pH value of 2-14, demonstrating very reliable stability and recycling ability.
