Аннотация: A methodology has been proposed and multifactor experiments have been performed to determine the effectiveness of simulation processes of the chemical immobilization of mercury in wastes implemented using the principles of green chemistry and taking into account various external conditions: the duration of interaction between mercury and sulfur, the amount of sulfur, the presence of water, and using methods to ensure constant updating of the contact area of phases (grinding of the reaction mixture: manually and with ball or vibration mills). As a result of a systems analysis of the results of simulating multifactor experiments using multivariant visualization tools of large data sets in the form of various diagrams (petal, ruled, bubble, and thermal), the following was established: the possibility of chemical immobilization for 90 min more than 95 wt % metallic mercury in contact with elemental sulfur with an initial mercury content of about 10 wt %, a stable immobilization result of 95 wt % or more mercury is achieved with an excess of sulfur of 3 g per 1 g of mercury and the reaction in a vibration mill, and the presence of a small amount of water (no more than 50 wt % of the weight of the reaction mass) positively affects the process of immobilization.
