eng Application of Copper Solid Amalgam Electrode for Determination of Fungicide Tebuconazole Pesticides are chemical substances which are used for preventing losses on culture plants, stocks of food, and feed. An excessive use of pesticides and other contaminants lead to an enormous burden for all components of biosphere in the final stage. Negative consequences of pesticide exposure (contamination of surface water, damage of ecosystems, and perishing of bees, and accumulation in the life systems etc.) led to an effort to reduce their use. Copper and tebuconazole together create a few different complexes at room temperature. The voltammetric behavior of tebuconazole was studied with help the newly developed mercury meniscus-modified copper solid amalgam electrode (inner diameter 1.5 mm). Differential pulse voltammetry (DPV) and cyclic voltammetry (CV) were applied for these purposes. The reaction mechanism was investigated using CV and elimination voltammetry with linear scan (EVLS). The optimum conditions for DPV determination of tebuconazole were found in Britton-Robinson buffer/methanol (1:1, v/v) of pH 6.3, initial potential and accumulation potential E acc=+400 mV vs. Ag/AgCl/3M KCl, scan rate 20 mV.s -1. Applying the prolonged accumulation time (60 s), the limit of detection 2.10 -7 mol.L -1 was achieved. The applicability of the developed method was verified on the analysis of the real soil solution sample. tebuconazole, differential pulze voltammetry, cyclic voltammetry
