| Abstract | The composites of graphene oxide (GO) decorated by MnFe2O4 have been synthesised via a green and facile strategy that the pristine GO/MnSO4 suspension prepared by Hummers method was directly utilised to convert into the GO-MnFe2O4 composites. The as-prepared composites were characterised using X-ray diffraction, scanning electron microscopy, Fourier transform infrared spectroscopy, Raman spectra and X-ray photoelectron spectroscopy. The results indicated that the GO-MnFe2O4 composites were successfully synthesised. The removal behaviours of Pb2+ and Cu2+ onto GO-MnFe2O4 were investigated, which indicated that the composites exhibited great adsorption property in aqueous solution. The adsorption process could be fitted well by the pseudo-second-order model and Langmuir isotherm. The thermodynamic studies indicated that the adsorption process of Pb2+ and Cu2+ onto GO-MnFe2O4 composites was spontaneous and endothermic in nature. Furthermore, the maximum adsorption capacities for Pb2+ and Cu2+ calculated from Langmuir model were about 263.85 and 103.41 mg/g at 318 K, respectively. Based on the results from the reusability experiments, the as-prepared GO-MnFe2O4 composites could be used as a potential adsorbent for removing Pb2+ and Cu2+ ions from aqueous solutions. |

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.
