ИСТИНА

The particulate matter (PM) contained in the dust, when weathered, pose a serious danger to the health of citizens and the ecology. Modification of humic substances with silanol derivatives leads to the possibility of their immobilization on various mineral particles, which can be used to bind dust and prevent wind erosion. Due to their lack of toxicity and resistance to biodegradation, they can be safely used on city streets using sprinklers. Previously, our laboratory developed methods and approaches for the synthesis of highly adhesive derivatives of humic substances - silsesquioxane-humic complexes (SSHC). The resulting complexes in the aqueous medium gradually condense with the formation of more curly and crosslinked structures. Spraying these complexes can lead to the binding of particulate matter especially coarse particles (≤10 μm – PM10) and fine particles (≤2.5 μm – PM2.5).
