Chemical properties


Green, yellow, white and red clay can be found in nature. The only active clay is green.

In the first chemical analysis for the given sample, the active and exchangeable acidity of the sample and its conductivity were performed. As for the active pH acidity in H2O, it is weakly alkaline and very stable based on exchangeable acidity, which is very good. The conductivity of clay is increased, indicating the presence of easily exchangeable cations in its composition

Table 2 shows the aluminosilicate analysis which indicates a slightly higher content of Fe2O3, K2O, and Na2O compared to some other clay. This composition shows its specificity of formation and action of this clay

Table 3 shows the total content of trace elements and uranium. The content of zinc and chromium is slightly increased in the sample of green clay. The content of other microelements is within normal limits. The lead content is low. The uranium content is also low and doesn’t pose any danger.

Based on chemical analyzes, green clay from the Zeo Kop Igros site is not a material that has an increased content of toxic elements
