摘要: Abstract Triclosan (TCS) has been widely used as an antibacterial and antifungal agent in household cleaning personal care products. The widespread use of TCS the products poses a potential risk to ecological system human health due its release into sediments, wastewater ground water resources causing chronicle toxicity aquatic organisms. However, no simple method is available for detection quantitative determination aqueous solution. A novel molecular imprinted surface plasmon resonance (SPR) chemical sensor was developed sensitive selective triclosan wastewater, using allylmercaptane modified gold SPR chip poly(2-hydroxyethyl methacrylate–methacryloylamidoglutamic acid) [p(HEMAGA)] nanofilm. unmodified surfaces were characterized by Fourier transform infrared (FTIR) spectroscopy, atomic force microscopy (AFM) contact angle measurements. validated according ICH guideline (International Conference on Harmonisation). linearity range limit obtained 0.05–1.0 ng/mL 0.017 ng/mL, respectively. nanosensor successfully applied samples exhibited excellent performance.
