    Study of properties of membranes based on carboxymethyl cellulose and chitosan

    Оne of the promising directions is the obtaining of biodegradable nanocomposite membranes, which allow to achieve a high level of purification and do not pollute the environment after their using. Anionic polyelectrolyte – Na-carboxymethyl cellulose with molecular weight Mw ~ 90000 and cationic polyelectrolyte – low molecular weight chitosan were used to create these membranes. Polymeric membranes were formed by mixing aqueous solutions of chitosan hydrochloride and Na-carboxymethylcellulose in different ratios. For study of the mechanical properties of membranes based on natural polymers such as chitosan and Na-CMC, the membranes were tested by the AG-Xplus apparatus by breaking. It was established that the membranes based on chitosan and Na-CMC have high mechanical strength. They can withstand a pressure of more than 5 atmospheres without damage. This makes it suitable for using in various conditions, including industrial ones. A barometric device was used to test the effectiveness of the obtained membranes. The study was conducted at different pressures (3, 4, 5 atm). It was established that membranes based on polyelectrolyte complexes with a stoichiometric ratio of anionic and cationic polyelectrolytes were the most productive.

    X-RAY structural study of membranes based on Na-CMC AND CS-Cl for water purification
    (КПІ ім. Ігоря Сікорського, 2024) Demchenko, Valerii; Shtompel, Volodymyr; Ovsiankina, Viktoriia; Broshko, Oleh; Krysenko, Tamara; Yurzhenko, Maksym; Romanyukina, Iryna
    The level of environmental pollution is increasing year by year. Solving this problem requires the development and application of new effective technologies and materials for wastewater treatment and processing of accumulated waste. One of the alternative directions is membrane technologies, in particular, the development of biodegradable nanocomposite membranes.
