Abstract

Sulfa drugs are mostly used as antimicrobial regents for treatment of several infections. Sulfa drugs can easily be accumulated in the human cells and can be leached out to cause water pollution. Nowadays, the removal of sulfa drugs from polluted wastewater is of research interest. According to our knowledge, application of bead-based biopolymers and metal organic framework (MOF) in the removal of sulfa drugs has not been investigated. The novelty in the current approach is to exploit a composite of chitosan and MOF for removal of sulfa drugs. The approach synthesizes a composite bead that is based on Fe-benzenetricarboxylic acid (Fe-BTC) a superiorly applicable MOF, and the biopolymers chitosan (Chs) and microcrystalline cellulose (MCC) for removal of sulfa drugs. The present study interests in the efficient removal of two kinds of sulfa drugs (sulphanilamide and sulfamethazine) by using the currently prepared bead. Chitosan (Chs) and microcrystalline cellulose (MCC) were used as sources for the bead. The materials interacted together to obtain Fe-BTC@Chs/MCC bead. Fe-BTC was well-distributed over the networked structure of Chs/MCC and filled the pore structure. Adsorption of sulfa drugs onto the synthesized beads was well-fitted to the pseudo-second order and isothermally to Langmuir. The affinity of Fe-BTC@Chs/MCC bead toward sulfamethazine was notably higher than that of sulphanilamide. Adsorption capacity of sulfa drugs onto Fe-BTC@Chs/MCC bead was decreased by only 16.4–15.5% after five reuse cycles which declare the substantial stability during the regeneration process.

期刊介绍: Cellulose is an international journal devoted to the dissemination of research and scientific and technological progress in the field of cellulose and related naturally occurring polymers. The journal is concerned with the pure and applied science of cellulose and related materials, and also with the development of relevant new technologies. This includes the chemistry, biochemistry, physics and materials science of cellulose and its sources, including wood and other biomass resources, and their derivatives. Coverage extends to the conversion of these polymers and resources into manufactured goods, such as pulp, paper, textiles, and manufactured as well natural fibers, and to the chemistry of materials used in their processing. Cellulose publishes review articles, research papers, and technical notes.
