Abstract
exhibited greater adsorption capacity than the MOF or the hydrogel alone in aqueous solution at most tested pH values (all except pH 13). At an initial MB concentration of 0.0096 mg/mL (30.014uM) and neutral pH conditions, this new hybrid presented the highest loading of MB among similar materials (MB adsorbed = 4.361 ± 0.092 mg MB/g Zr, partition coefficient = 0.172 ± 0.004 mg/g/uM) and largely retained its adsorption capacity under varied conditions (pH 1-13 and 0.2-1.0M NaCl), rendering possible applications in drug delivery and the removal of tumor contrast agent/dye with minimal leakage due to its broad chemical stability.
