Systemic Approach to Design of Gel Compositions of Combined Effect

Abstract

A systematic approach to desing of gel compositions of combined effect has been proposed and practically tested. The scientific approach is based on the physical and chemical analysis of polycomponent systems containing the main components of the compositions. This approach allows achieving the maximum result with rational use of raw materials. Solubility in the Vilagin – Surfactant "Progress" – Sodium citrate – Coriolate – water system at 25 ° C was studied. The components of the system were selected in such a way that their mixtures showed disinfectant and deactivation properties. Vilagin is a highly effective bactericide, but its low solubility in water significantly limits its application. It is found that the surfactant "Progress" is a fairly good homogenizer of the Vilagin-water stratifing system, and does not negatively affect on its bactericidal activity. Sodium citrate and corylate are capable of binding radioisotopes of alkaline earth and heavy metals to soluble complex anions that are removed from the surface to be treated together with the solution. It is found that the value of the homogeneous region of the system depends to a greater extent on the concentration of Vilagin and salts. The first component is insoluble in water, and the salts are sparingly soluble. The viscosity of the obtained gels depends on the ratio of Vilagin and surfactant. The components concentration intervals at which there are stable gels that possess not only disinfectant, but also deactivation properties are found. Gel mixtures, which compositions are located near the binodal curve, can be diluted with water over a wide range of concentrations to obtain solutions with a specified content of Vilagin and salts. It is proved that the developed gel compositions are effective in small concentrations in a short time, have low toxicity, multifunctionality, good solubility in water, and a long shelf life of concentrates.
