Abstract
Ecological decontamination solutions are widely used in various fields of activity especially in this period when many countries in the world are implementing at macro level the concept of sustainable development. The use of detergents in the process of R.B.C. decontamination led to in-depth analyzes of the absorbent properties of organic products. These products have the ability to partially or completely remove detergents from wastewater resulting from decontamination, thus reducing pollution by environmental factors. The present paper aimed at the comparative analysis of the absorbent properties of a power plant ash and diatomite ore. Also, some experiments were performed on the biodegradability of detergents considered in the study and the interpolation of data analyzed by spline functions.
