Investigation of the Physicochemical Relationships of the Production of a Polyelectrolyte Complex Based on Polydialldimethylammonium Chloride and Sodium Lignosulfonate as an Effective Inhibitor of Salt Deposits.

A method is proposed for the production of an inhibitor of salt deposition based on a polyelectrolyte complex, including an anionic natural polymer (sodium lignosulfonate) and a cationic synthetic polymer (polydiallyldimethylammonium chloride) as initial components. A stable polyelectrolyte complex was produced by selecting the molar ratios of the anionic and cationic components by impedance spectroscopy, which involves measurement of the dependence of an electrochemical cell on the frequency of the alternating current. The effectiveness of the polyelectrolytic complex as inhibitor of salt deposition in waters with various compositions under conditions of rising temperatures was demonstrated experimentally.
