Organic Linkers and Their Modified Nanoparticles for Colorimetric Monitoring Devices for Inorganic Water Contaminants

A large number of inorganic contaminants have been discharged into the surrounding waters as a result of expanding industry, mining industries, and urbanization so they have a fatal influence on the well-being of people and developed significant environmental harm. Due to their strong interactions with the earth's framework and increased danger to the surroundings, heavy metals make up the majority of inorganic contaminants. Even Nevertheless, when ingested below permitted levels, several of these metal particles are crucial for biological activities. Earlier, many traditional spectroscopic like ICP-MS, AAS were used to quantify these contaminants. However, these methods of analysis demand intricate preparation of samples often are laborious, expensive, as well as tedious. Their application for in-the-field testing for heavy-metal ions is constrained by these drawbacks. Because of its excellent specificity, sensitivity, and price effectiveness, unaided colorimetric sensing is now widely used for monitoring pollution to allow quick in-the-field identification of contaminants. This chapter will examine the newly developed organic linkages and their modified nanoparticles utilized to create inorganic pollution sensors and will provide an overview of the novel approaches for the onsite evaluation of these metallic ions utilizing reagent kits and test strips.
