U.V. Spectrophotometric Method towards the Selective Detection of Imidacloprid Using Organic Nanoparticles of (E)-(4-nitrophenyl)-1,1-diamino-2,3-diazabuta-1,3-diene
Pesticide detection is a major concern nowadays because of their adverse negative effects to living organisms and the environment. Therefore, to overcome such challenge, in our recent study, we synthesised (E)-(4-nitrophenyl)-1,1-diamino-2,3-diazabuta-1,3-diene based organic nanoparticle (ONP) senso...

| Summary: | Pesticide detection is a major concern nowadays because of their adverse negative effects to living organisms and the environment. Therefore, to overcome such challenge, in our recent study, we synthesised (E)-(4-nitrophenyl)-1,1-diamino-2,3-diazabuta-1,3-diene based organic nanoparticle (ONP) sensor via employing a green strategy. Re-precipitaion method was used to form organic nanoparticles. TEM analysis reveals that the average size of particle is 23.86 nm.The prepared ONPs showed high selectivity towards imidacloprid, a neonicotinoid pesticide. It was determined that the limit of detection was 0.82 µM and The association constant was calculated to be 9.68x107 M-1. The pH (basic and acidic) and temperature (15-55 °C) studies were also carried out which resulted that these ONPs were stable in the range of 6-12 pH and within 15-55 °C temperature range. |
