▎ 摘　　要

The heavy metal ions and pollutant are considered as a one of the major problem in environmental contamination. Hence detection of trace level pollutant becomes a more research area in today. Graphene oxide nanocomposite is important in sensor research; it has special physical and chemical properties. Modified graphene oxide nanocomposite can be absorbing pollutant material ions in a high efficiency and selectivity. In this review focused on the Preparation of different type of graphene oxide nanocomposite and it characterized by different spectroscopy. Minimum number of graphene nanocomposite sensors with low limit of detection was reported to detect towards pollutant.
