Investigation of the capsulated material properties for possibility of using it as recoverable raw materials

Abstract

Among the methods used to neutralize oil-polluted soils, the physic-chemical method (reagent encapsulation technology) based on the encapsulation of a pollutant is the simplest and relatively inexpensive. Applying reagent encapsulation technology neutralizes oil-polluted soil with toxic properties by obtaining fine, solid formations with a high degree of the pollutant isolation. Considering the volumes of annual pollution of soil with oil products, it is necessary not only to neutralize oil-polluted soil promptly, but also to dispose obtained neutralization products (encapsulated material) properly by using it as recycled raw materials. That is why it is very important to investigate the properties of the encapsulated material obtained. Considering the possible areas of the encapsulated material application, the main requirement should be to preserve the tightness of the microcapsule shells, when microcapsules enter the aqueous or acidic medium as the pollutant is located inside the shells. The purpose of the article is an experimental study of the properties of the encapsulated material on the effects of moisture (destruction of microcapsules while in the aquatic environment), the effect of temperature fluctuations, and resistance to acidic and mechanical effects (strength). The method of conducting experimental studies of the encapsulated material properties, the effects of natural and man-made factors has been considered. Experiments have shown that the microcapsules under study hold the pollutant inside reliably and that they are not subject to destruction during temperature fluctuations, being in aqueous or acidic medium, and also, they withstand high mechanical stress.Among the methods used to neutralize oil-polluted soils, the physic-chemical method (reagent encapsulation technology) based on the encapsulation of a pollutant is the simplest and relatively inexpensive.
