Abstract:A kind of portable device for measuring concentration of pesticides used with enzyme sensor was designed. It included screen-printed enzyme electrode, signal conditioning circuit and MCU C8051F040. The preparation of enzyme electrode made the coated resistance of charge transfer reduced, charge transfer accelerated; and a reliable liner relationship between the inhibition of enzyme and log [carbaryl] was obtained from 5ng/mL to 2μg/mL, with the detection limitation of 1.7ng/mL. Response time of the device was less than 161s. The size of the device was small and the power was supported by battery. It provided a portable device for rapid measuring and spotty concentration of pesticide in μg/L level.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
