| Abstract | Recent controversy over the discovery of clouding agents containing the banned chemical di(2-ethylhexyl) phthalate in beverages in 2011 in Taiwan has caused public concerns. For the detection of dimethyl phthalate (DMP) in environment water samples, an indirect competitive enzyme-linked immunosorbent assay (ic-ELISA) was developed in this paper. Dimethyl 4-aminophthalate (4-DMAP) was covalently attached to bovine serum albumin as immunogen by a diazotization method. The conjugation of DMAP and ovalbumin as coating antigen was obtained in the same way. Polyclonal antibody was obtained from New Zealand white rabbits. Under the optimized conditions, DMP was detected in the concentration range of 0.02–419 ng/mL with a detection limit of 0.01 ng/mL. The proposed method has been applied to the analysis of river water, lake water, and rain water samples. Satisfactory recoveries were obtained ranging from 90.6% to 105.5%. The cross-reactivities of the anti-DMP antibody to seven structurally related phthalate esters were below 10%. The data demonstrated that the ic-ELISA method described in our study is a simple, sensitive, and specific method and showed that this assay is a reliable tool to detect DMP in water samples. |

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.
