3D-PRINTED POLYLACTIC ACID MEMBRANES FOR REMOVING VALUABLE AND TOXIC COMPONENTS FROM AQUEOUS SOLUTIONS

3D-PRINTED POLYLACTIC ACID MEMBRANES FOR REMOVING VALUABLE AND TOXIC COMPONENTS FROM AQUEOUS SOLUTIONS

3D printing allows one the production of membranes of any shape and size according to consumer requirements. The work solves the problem of studying the separation properties of filtration membranes, which, unlike the known ones, were obtained via one stage. Polylactic acid (polylactide, PLA) and it...
