Qualitative and quantitative research on pesticide chemical admixture in liquids

Express electric monitoring of a chemical composition is proposed to be conducted by identifying an electric index that corresponds to regulatory chemical threshold concentration and is selective for the monitored substance. Theoretical and experimental possibilities of combining the known classical methods have been scrutinized in order to improve the characteristics of an output signal for determining the monitored substance concentrations - the pollutants in liquids (juices, vegetable and fruit samples or wastewaters). The monitor-technique implies the measurement of a reactive immitance component (a component of complex conductivity) at the defined frequency value selective for copper sulfate that is compared to the relevant regulatory value identified in the process of studying a standard pattern with the given ThC.
