Abstract:Herein, a facile and low-cost route was used to prepare Polydopamine@Zeolitic Imidazolate Framework-67 (PDA@ZIF-67). The structure, morphology, surface functional groups and particle size distribution of PDA@ZIF-67 were studied using FTIR, FESEM, EDS, and BET analyses. The specific surface area and diameter of PDA@ZIF-67 were equal to be 78.203 m2/g and 4.179 mm, respectively. The PDA@ZIF-67 was used as an adsorbent for the adsorption of methylene blue dye. The results show that the maximum adsorption effici… Show more
“…Then, at pH 4, an uptake ∼35% was determined, observing a slightly decreasing trend with increasing pH until reaching ∼27% at pH 12. These results were in line with published results on the MB adsorption onto different zeolites 47 and conrmed the signicance of pH on the adsorption of organic and inorganic pollutants on zeolitic materials. 48 The point of zero charge (pH pzc ) corresponds to a neutral surface charge.…”

Besides being hazardous to humans and aquatic organisms, dyes present in water reservoirs limit sunlight's availability to aquatic plants and animals, making significant impact on their growth and development.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
