FIELD: process engineering. n SUBSTANCE: invention relates to membrane technology, particularly, to production of antibacterial polymer membranes to be used in water and aqueous solution treatment in food and pharmaceutical industries, and medicine. Proposed method comprises making polymer solution, forming of polymer membrane and processing with antibacterial substance. Produced membrane is dried, rinsed with water and subjected to final drying. Said antibacterial substance represents composition containing the following components in wt %: 5-10 of poorly soluble or insoluble slats of silver, 2-25 of formic acid an 65-93 of water. n EFFECT: prolonged antibacterial properties. n 9 ex |
