| Abstract | An amino-functionalised magnetic mesoporous silica was prepared through one-step copolymerisation method. Morphology, characteristic-group composition, microscopic morphology and specific surface area of the magnetic mesoporous silicas were analysed by scanning electron microscope, Fourier transform infrared spectroscopy, transmission electron microscope and nitrogen adsorption–desorption. The prepared magnetic silica MS-1 had the characteristics of micron-sized particle size, exceptional long-range ordered pore structure, and as high as 114.6 m2/g in specific surface area. The adsorption kinetics of tetracycline (TC) and Cu(II) onto magnetic mesoporous silicas in sole and binary system were also investigated. MS-1 could adsorb both of TC and Cu(II) with adsorption capacities of 35.14 and 23.65 mg/g, respectively, which were enhanced in binary systems about 26.5 and 19.7%, respectively. The solution pH significantly affected the adsorption because of the pH-responsive speciation of TC, TC–Cu(II) complex and the amine groups on adsorbent. This work proposed a potential effective method for the synergistic adsorption of antibiotics and heavy metals from aquatic environment. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
