| Abstract | In this study, un-hydrolyzed (UHS) biomass residue generated from enzymatic hydrolysis of corn stover was used for activated carbon production. Activated carbons were prepared by high-temperature chemical activation method, with phosphoric acid and Zinc chloride (ZnCl$_{2}$) as the activation agents. A factorial design was used to optimize the activation process, and five different parameters (pretreatment methods, impregnation ratio, activation time, activation temperature, and temperature increasing rate) were analyzed with respect to their influence on BET surface area and pore volume. At optimized activation condition (i.e., co-precipitation pretreatment method, impregnation ratio 1.5, activation time 60 min, activation temperature 500 °C and heating rate 60 °C/min), activated carbon is obtained with surface areas and pore volumes approaching 1117 m$^{2}$/g and 0.12 cm$^{3}$/g, respectively. The capacity of methylene blue adsorption from aqueous solutions could reach 279 mg/g and adsorption isotherm fits Langmuir model. Iodine number of the prepared activated carbon was comparable to that of commercially available material. The prepared activated carbon was characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD) analysis, Fourier transform infrared (FTIR) spectroscopy, thermo-gravimetric analysis (TGA), and energy-dispersive spectrometry (EDS). |

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.
