IntroductionCurrently the Scientists' and technologists' attention are focused on finding ways to integrated use of natural resources and the creation of low-waste and non-waste technology with the rational using of recycled materials. One of the effective ways to solve this problem is to obtain ion-exchanging polymers based on chemical waste. It is known that the application of ion exchange resins leads to a simplification of processes for separating ion mixtures, purification and solutions concentration of nonferrous and rare metals ions contained in industrial waste waters and hydrometallurgical production (Abdutalipova et al., 2010, p. 7).Great practical interest in the manufacture of ion exchange resins are chemical wastes such as wastes oil, gas and hydrolysis industry. The striking example is the furan derivatives, part of furfural, for the production of our country which is huge reserves of plant materials including waste cotton industry. The presence structure of furan heterocyclic nucleus make to get ion exchange resins allows obtaining a universal chemical heat resistance and mechanical strength (Abdutalipova et al., 2010, pp. 60-62). In this regard, we have obtained a number of new ion exchanging polymers based on furfural and investigated their basic physical and chemical properties.
There are investigated sorption and desorption characteristics of phosphate cation-exchange resin among metals: copper, nickel, cobalt, an uranyl-ion depending on pH-environment, the ionic form of cation-exchange resin, concentration of investigated cations. Interaction of cation-exchange resin in Na- and H-forms with solutions of salts sulphate of copper, nickel, cobalt, chloride sodium, calcium and nitrate of uranyl is studied. It is shown, that ions of copper, nickel, cobalt and an uranyl-ion by phosphate cation-exchange resin sorb at the expense of an ionic exchange and partially at the expense of formation of coordination communications with ionogenic group of cation-exchange resin. A study of the sorption of uranyl ions depending on the concentration of uranyl nitrate in the range of 0.01-0.1 N showed that with an increase in the concentration of uranyl in the studied interval, the value of sorption of uranyl increases slightly. The studied phosphate cation exchanger has a sufficiently high sorption and desorption ability to the ions of the tested metals.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
