| Abstract | Remediating soils contaminated with heavy hydrocarbons (C12–C40) from petrochemical exploration activities is a major environmental challenge across the globe. This study evaluated microwave irradiation in the presence of nano- and macro-scale graphitic additives as a rapid remediation technology for removing heavy hydrocarbons from soil. Adding inert materials (i.e., glass wool fibers or washed silica sand) as controls had no effect on total petroleum hydrocarbons (TPH) removal upon microwave irradiation. Carbonaceous nanomaterials (i.e., carbon nanotubes, graphene nanosheets, and carbon nanofibers) because of their favorable dielectric properties showed extraordinary heating performances when mixed with soil and microwave irradiated. As a result, adding these carbonaceous nanomaterials to contaminated soils removed more TPH compared with macro-scale carbonaceous additives. TPH concentrations decreased from 11 000 to between 2000 and 6000 mg TPH kg−1 soil within one minute using carbon nanomaterial additives and a 2.45 GHz, 1000 W conventional microwave oven. In separate experiments, this technology decreased TPH from 2500 to 650 mg TPH kg−1 soil from soils containing recalcitrant, non-biodegradable fractions of TPH. Large scale microwave systems are available and hold promise for remediating soils when used in conjunction with carbon nanomaterials. |

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.
