Reaction of 2,6-dichloroquinone-4-chloroimide (Gibbs reagent) with permethrin – an Optical Sensor for rapid detection of permethrin in treated wood
Chemistry Central journal, 2013Co-Authors: Mohamad Nasir Mat Arip, Lee Yook Heng, Musa Ahmad, Siti Aishah HasbullahAbstract:A novel Optical Sensor for the rapid and direct determination of permethrin preservatives in treated wood was designed. The Optical Sensor was fabricated from the immobilisation of 2,6-dichloro-p-benzoquinone-4-chloroimide (Gibbs reagent) in nafion/sol–gel hybrid film and the mode of detection was based on absorption spectrophotometry. Physical entrapment was employed as a method of immobilisation. The Sensor gave a linear response range of permethrin between 2.56–383.00 μM with detection limit of 2.5 μM and demonstrated good repeatability with relative standard deviation (RSD) for 10 μM at 5.3%, 100 μM at 2.7%, and 200 μM at 1.8%. The response time of the Sensor was 40 s with an optimum response at pH 11. The Sensor was useful for rapid screening of wood or treated wood products before detailed analysis using tedious procedure is performed. The validation study of the Optical Sensor against standard method HPLC successfully showed that the permethrin Sensor tended to overestimate the permethrin concentration determined.

Optical Sensor for Real-Time Reconstruction of Distortions on Electronically Steered Antenna
IEEE Photonics Technology Letters, 2008Co-Authors: Guillaume Lesueur, Hervé Gilles, Sylvain Girard, T. Merlet, M. QuéguinerAbstract:A measurement system based on a set of Optical fiber probes has been implemented and tested for real-time reconstruction of mechanical distortions of electronically steered antenna arrays. Such an Optical Sensor allows a full-reconstruction of the emitting surface topography, which is necessary to electronically compensate the degradation of the radiating pattern under mechanical distortions of its structure.
