A method for trace determination of the pesticide Diazinon using adsorptive square-wave stripping voltammetry (AdSWSV) at the dropping mercury electrode (DME) was described. The pesticide was accumulated at the DME and a well-defined stripping peak was obtained at -1012 mV vs Ag/AgCl/KCI electrode in 0.4 N ammonium acetate electrolyte soluti pH 4.3. Peak current was linear over Diazinon concentration range of 800 – 3200 ppb. Detection limit was 16.49 ppb. Effects of some other pesticides (Chlorpyrifos and Cypermethrin) on Diazinon peak and the recovery of Diazinon from artichoke leaves were studied. The method was extended to the determination of Diazinon in artichoke leaves. The recovery of Diazinon from artichoke leaves was 90.31 - 93.55%. Detection limit was 29.82 ppb. Method had high repeatability and selectivity.

In this paper, microelectromechanical systems (MEMS) technology was used to fabricate a novel extrinsic fiber Fabry–Perot (EFFP) strain sensor; this fiber sensor is applied to measure load with higher precision for a small structure. The sensor cavity consists of two Fabry–Perot (FP) cavity mirrors that are processed by surface micromachining and then fused and spliced together by the silicon–glass anode bonding process. The initial cavity length can be strictly controlled, and the excellent parallelism of the two faces of the cavity results in a high interference fineness. Then, the anti-reflection coating process is applied to the sensor to improve the clarity of the interference signal with the cavity, with its wavelength working within the range of the C + L band. Next, the sensor placement is determined by the finite element software Nastran. Experimental results indicate that the sensor exhibits a good linear response (99.77%) to load changes and a high repeatability. Considering the strain transfer coefficient, the sensitivity for the tested structure load is as high as 35.6 pm/N. Due to the miniaturization, repeatability, and easy-to-batch production, the proposed sensor can be used as a reliable and practical force sensor.
