Keywords Graphene oxide  Inorganic pollutants  Nanocomposites  Sensors Heavy metal detection Introduction Graphene oxide (GO) is a 1-atom-thick planar sheet of sp -bonded carbon atoms ordered in a two-dimensional honeycomb lattice and is the basic building block of carbon allotropes [1]. Owing to its excellent mechanical, thermal, electrical and optical properties, it can be applied for versatile applications in the fields of electrocatalysis, sensors, electrochemical devices, drug delivery, gene transfection, and biosensing [2, 3]. In recent years, GO-based metal nanocomposites have attracted much interest from researchers because of their unique and outstanding physico- chemical properties towards their applications. Among several metal nanoparticles, silver (Ag), gold (Au) and platinum (Pt) nanoparticles have attracted much attention for the fabrication of GO sheets, due to their wide-ranging applications [4, 5]. Due to their high catalytic activity and electronic and optical properties, silver nanoparticles (AgNPs) have attracted attention in various areas of applications like catalysis [6], chemical sensing [7], antibacterial [8], and biosensing [9]. Numerous methods have been reported in the literature, i.e. chemical and physical approaches to synthesizing AgNPs, but they suffer from several disadvantages concerning the sources of applicability and reproducibility. Preferred chemical methods have resulted in the production Research on Chemical Intermediates Springer Journals
