AB  - The study's primary goal is to determine carbamate pesticide methomyl's kinetic parameters and degradation efficiency from water solution by direct electrochemical oxidation using IrOX anode. Also, define the dependence of the efficiency of methomyl decomposition by direct electrochemical oxidation on the initial concentration of pesticide and electrolyte, applied current, and pH value. The results of methomyl degradation by direct electrochemical oxidation obey the pseudo-first kinetic order. Ultraviolet-visible (UV-Vis) spectroscopy followed the methomyl concentration during the study. The degradation products were studied using the Fourier transform infrared (FT-IR) spectroscopy. Also, this study determines the energy consumption and optimal initial conditions. The phytotoxicity of pesticide and degradation products was studied using mung beans.

AB  - Introduction/purpose: In this study, we investigated the possibility of removing the organophosphorus pesticide malathion from water using a new adsorbent based on the biowaste of river shell shards from the Anodonta Sinadonta woodiane family, a material that accumulates in large quantities as waste on the banks of large rivers. Two adsorbents were tested - mechanically comminuted river shells (MRM) and mechanosynthetic hydroxyapatite from comminuted river shells (RMHAp). Methods: The obtained adsorbents were characterized and tested for the removal of the organophosphorus pesticide malathion from water. In order to predict the optimal adsorption conditions using the Response Surface Method (RSM), the authors investigated the influence of variable factors (adsorption conditions), pH values, adsorbent doses, contact times, and temperatures on the adsorbent capacity. Results: The best adsorption of malathion was achieved at mean pH values between 6.0 and 7.0. The adsorption data for malathion at 25, 35, and 45 °C were compared using the Langmuir, Freundlich, DubininRadushkevich (DR), and Temkin isothermal models, as well as pseudofirst order, pseudo-second order and Elovic kinetic models for modeling adsorption kinetics. The maximum Langmuir adsorption capacity for MRM and RMHAp at 25 °C was 46,462 mg g-1 and 78,311 mg g-1 , respectively. Conclusion: The results have showed that malathion adsorption on both adsorbents follows the pseudo-second kinetic model and the Freundlich isothermal model. The thermodynamic parameters indicate the endothermic, feasible, and spontaneous nature of the adsorption process.
