СОРБЕНТЫ НА ОСНОВЕ СОПОЛИМЕРОВ ПРОИЗВОДНЫХ АКРИЛОВОЙ КИСЛОТЫ, АКРИЛАМИДА И НЕОРГАНИЧЕСКИХ НАПОЛНИТЕЛЕЙ

Abstract

A new bisacrylamide, containing a thiocarbamidyl radical is synthesized and later used as a sealant to obtain copolymers based on acrylic acid (AT), diatrium salt (Na-AT) and acrylamide (AA) in water. The copolymer, depending on the number of sutures, the dynamics of its absorption over time have been studied. The ability of a copolymer water jelly to combine with inorganic silicate fillers has been studied. As inorganic silicate fillers, Montmarrylonite clay, aerosil - 200, aerosil - 300, white soot, kaolin were used: The dynamics of water absorption of the composite (JMC) combined with the inorganic filler of the water-copolymer of the copolymer have been studied. The results are presented in this article. The compound developed using kaolin has been shown to have a higher water absorption. The water absorption capacity of the PMB has been studied by gravity. Sorbent samples were developed in combination with sand, 0.3-0.5 mm particles of PMB, river and sea, which is recommended to be used to remove heavy metal ions from the effluent, bringing their concentration in the water to the allowable limits. Given the sorption properties of the developed sorbents, it is recommended that they be used to remove ions of other metals (Со+2, Ni+2, Cd+2, Pb+2, Hg+2 , etc.) from the aqueous medium. The sorption capacity of the sorbents presented in this work is mainly due to the multifunctionality of the copolymer, as well as the stability of the compounds formed by the interaction of the functional groups of the copolymers with the metals. As shown in this work, the nature and structure of inorganic fillers are important for the quantitative removal of metal ions from wastewater.
