| Abstract | Sample preparation is one of critical steps in Multiresidue Analysis of Pesticides. In this paper, the sample preparation methods for Multiresidue Analysis of Pesticides in vegetables were studied by using cucumber and leek was used as materials. Results show that the optimum sample preparation conditions for normal vegetables were as follows: The ratio of acetonitrile to water was 3∶1 during C18 solid-phase extraction. The pH values prior to homogenization and liquid extraction were 7 and 5, respectively. The matrix interference was complex when the samples as chinese chive were prepared by using normal method. Treatment of adding small amount of phosphoric acid before homogenizing could effectively abate matrix interference, which lead to the recovery of more than 90% pesticides among 76 different type of pesticides detected range from 70% to 120%. |

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.
