HUMIC SILANOL DERIVATIVES, METHOD FOR PRODUCTION AND USE THEREOF |
摘要 |
FIELD: chemistry.SUBSTANCE: invention relates to environmental protection technology and chemistry of organosilicon compounds and can be used in purifying contaminated ground water, bottom sediments and soil by establishing reaction barriers. Disclosed is a method of producing a humic derivative by reaction of a humic substance with aminoalkoxysilane in an aqueous medium, followed by distillation of the aqueous solvent and heating the obtained substance at 120-150°C. The invention also discloses the humic derivative obtained using said method and versions of uses thereof. The obtained coating is resistant to possible changes in acid-base or redox ambient conditions, which prevents the possible release of associated ecotoxicants.EFFECT: present method enables to obtain humic silanol derivatives capable of strong sorption on mineral hydroxyl-containing solid surfaces, which can be used in both dissolved and immobilised form.13 cl, 10 dwg, 7 tbl, 8 ex |
