Recently,carbon-based nanomaterials have been attracted much interest among the scientific community due to its extraordinary properties and applications. Mostly fluorescent carbon are prepared from commercially available precursors. In this work, develop a new strategy for producing nanoparticles (carbon dots) using phosphoric acid as an activating agent water hyacinth present in Assam, India. These show green fluorescence under UV light, sizes found below 10 nm. dots applied sensor detecting herbicide (pretilachlor). The developed PL is exclusively selective sensitive detection of herbicide, limit be 2.9 μM.This also tested real samples like soil contaminated with pretilachlor.
