Abstract
Изобретение относится к области получения полимерных сорбентов и может быть использовано для очистки сточных вод от различных загрязнителей, в том числе органических красителей. Способ включает интеркалирование бутадиенового каучука (БК) в межслоевое пространство бентонитовой глины, модификацию смеси БК и бентонита треххлористым фосфором путем окислительного хлорфосфорилирова-ния в присутствии кислорода, с дальнейшим гидролизом продукта реакции. В результате получают гидрофобный материал за счет сшивки макромолекул полимерной матрицы, а выделение HCl при модификации с использованием PClспособствует активации бентонита и увеличению адсорбционной способности композита благодаря большему разрыхлению неорганического компонента. По изобретению получают гибридный композиционный сорбент, обладающий сорбционной активностью по отношению к органическому красителю Родамин 6Ж, сорбционная емкость сорбента составляет 32,2 мг/г.The invention relates to the field of polymeric sorbents and can be used to clean wastewater from various pollutants, including organic dyes. The method includes the intercalation of butadiene rubber (BC) into the interlayer space of bentonite clay, modification of a mixture of BC and bentonite with phosphorus trichloride by oxidative chlorophosphorylation in the presence of oxygen, with further hydrolysis of the reaction product. As a result, a hydrophobic material is obtained by crosslinking the macromolecules of the polymer matrix, and the release of HCl when modified using PCl promotes the activation of bentonite and an increase in the adsorption capacity of the composite due to the greater loosening of the inorganic component. According to the invention, a hybrid composite sorbent is obtained, having sorption activity with respect to the organic dye Rhodamine 6G, the sorption capacity of the sorbent is 32.2 mg / g.
