title: Sensitive chemi-sensor for environmental applications as marker of chloroform in aqueous solution.
abstract: Sensor technology is a talented progression in the fundamental science and has vital role in the environmental and health monitoring. A lot of sensor materials with different sensitivities have been exposed but the prospective for industrial development as sensors and environmental supplement are still limited. Chloroform chemi-sensor has been fabricated by proficient exploitation of CuO microsphere as redox mediator. CuO microsphere showed good sensitivity (1.497 μM cm(-2) mM(-1)) and lower limit of detection (LOD=0.08 mM) with linear dynamic range (LDR) of 0.13 mM to 0.66 M in short response time (10.0 s). The hydrothermally synthesized CuO microsphere were characterized by using field emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and UV-vis spectra. XRD and FTIR approved that synthesized product is well crystalline, single phase monoclinic CuO. Morphological investigations revealed that CuO composed of nano-block which arranged and structured themselves in a proper manner to give sphere like micro-structures.
