Selective dye adsorption by highly water stable metal-organic framework: Long term stability analysis in aqueous media

Zr‐Based MOFs with High Drug Loading for Adsorption Removal of Anti‐Cancer Drugs: A Potential Drug Storage

“…Additionally, they found that the solvent utilized as medium for encapsulation shows a critical effect on the adsorption properties of the synthesized MOFs due to the creation of a competitive adsorption process with drug molecules . In our previous work, the structural stability of UiO‐66 against water was studied for one year, which the results indicated that this MOF is highly stable against water for a long time and the BET surface area of that show a small reduction . Therefore, in the present work a series of UiO‐66‐drived MOFs including UiO‐66‐NH 2 , glycidyl methacrylate functionalized UiO‐66‐NH 2 (UiO‐66‐GMA) and ethylenediamine functionalized UiO‐66‐NH 2 (UiO‐66‐EDA) was chosen for adsorption of two anti‐cancer drugs like as methotrexate (MTX) and curcumin (CUR).…”

“…Despite of several outstanding benefits, MOFs have some limitation like as toxicity, low biocompatibility, low chemical stability, and low thermal stability, which restricted their application in drug adsorption and delivery . Among the numerous synthesized MOFs, Zr‐based MOFs have been widely used as drug adsorbent material because of their high chemical stability specially water stability, high thermal and mechanical stability, high level of biocompatibility, and high drug‐loading capacity . For example, Cunha et al synthesized a series of UiO‐66‐drived MOFs with different functional groups like as ‐Br, –H, ‐NH 2 , ‐NO 2 , ‐2OH, ‐Cl, ‐2CH 3 , ‐CH 3 , and ‐2CF 3 , and used them for encapsulation of anti‐inflammatory ibuprofen and the cosmetic caffeine.…”

“…[8,17] Among the numerous synthesized MOFs, Zrbased MOFs have been widely used as drug adsorbent material because of their high chemical stability specially water stability, high thermal and mechanical stability, high level of biocompatibility, and high drug-loading capacity. [18][19][20][21][22] For example, Cunha et al [20] synthesized a series of UiO-66-drived MOFs with different functional groups like as -Br, -H, -NH 2 , -NO 2 , -2OH, -Cl, -2CH 3 , -CH 3 , and -2CF 3 , and used them for encapsulation of anti-inflammatory ibuprofen and the cosmetic caffeine. The results exhibited that the drug loading is optimized when UiO-66 grafted with functional groups that have low hydrogen bond acceptor abilities.…”

Facile synthesis of a triptycene‐based porous organic polymer with a high efficiency and recyclable adsorption for organic dyes

“…At this point, several technologies have been applied in industry to treat the dye‐containing wastewaters; these technologies include membrane separation, chemical precipitation, flocculation–solidification, oxidation, and electrochemical processes . Among them, the use of adsorbent to remove dyes from wastewater is still considered the most promising method because it is highly effective, economical, and convenient …”

“…9 Among them, the use of adsorbent to remove dyes from wastewater is still considered the most promising method because it is highly effective, economical, and convenient. 2,10,11 Traditional porous adsorbents, such as zeolites, 12 oriented clay, 13 montmorillonite, 14 molecular sieve, 15 and activated carbon, 16 have been successfully applied to remove the organic dyes, but their low adsorption capacity (q e ) and poor reusability have driven researchers to explore more efficient adsorbents further. 17 Therefore, the synthesis of novel adsorbents with high dye q e and removal efficiency (R) values is still of great significance and a matter of practical importance.…”
