Abstract:
Antibiotics are one of biggest cause in polluting water. Due to human consumption of antibiotics, 30-92 % of active compounds of antibiotics are excreted and enters into sewage of residential system. This implies that city sewage plants are full of such medicines. Antibiotics are also used to treat the animals which release them on land and eventually they get into water bodies like river etc. Tetracycline is one of those well-known and well used antibiotic. Therefore there is concern about effective remediation and treatment is needed. For adsorption of organic components, large surface area material is needed and photocatalysis work on advanced oxidation process (AOP) that needs light absorptive material that generate charge carriers which further initiate the reaction for decomposition of organic molecules. Now a days metal organic frameworks (MOFs) are there to provide such class of adsorbent that have large ability for adsorption of different molecules owing to large surface affinity. MIL-Fe (MOF) is newly attractive porous material considered as clean environmental remedy. The doping of another entity (metal oxide) into MOF MIL-Fe allows to manipulate the photocatalytic properties. The doping of graphene and graphene like material (g-C3N4) would minimize the recombination of hole-electron pairs, therefore it increase photocatalytic activity and can be used in selective oxidation of alcohols into ketones or aldehydes with maximum conversion. In present study, a novel photocatalyst and adsorbent has been developed by hydrothermal and in situ method.MOF MIL-53(Fe) and its hybrids with graphene oxide/g-C3N4 /metal oxide for removal of antibiotic (Tetracycline) from water. SEM, XRD, FTIR and TG/DTA suggest successful synthesis of photoadsrobent. UV-VIS spectrophotometry is used to determine degradation performance of photoadsorbent. More than 50% of Tetracycline has been degraded by this method which can open new pathways of technology to effective remediation of antibiotic in aquatic environment Keywords: Metal Organic Framework, Solvothermal Method, Adsorption, photoadsrobent.
