Analyzing the Efficiency of Using Different Chemical Compositions for Intensifying the Phytoextraction Processes of Mercury and Other Heavy Metals Based on Multivariate Image Tools

A method is proposed and multifactorial experiments are carried out to determine the effectiveness of various compositions of chemical additives for intensifying the processes of phytoextraction of mercury and other heavy metals from soils. White creeping clover (lat. Trifolium repens L.) is used as the object of experiment. As a result of a systematic analysis of the results of experiments using the tools of multivariate visualization of large data arrays in the form of various diagrams (petal, line, bubble, and thermal), the following was established: the presence of a positive effect of monoethanolamine salt of thioacetic acid and sodium thiosulfate on phytoextraction of mercury; a pronounced positive effect of Trilon B on the phytoextraction of heavy metals, simultaneously accompanied by a destructive effect on the growth and development of plants; a positive effect on the condition of plants of phytohormone and iron chelate supplements; and the ability of oxyethylidene diphosphonic acid to protect plants from the negative effects of heavy metals.
