membrane ultrafi ltration

Prospects for the use of polymer-containing materials and sorbents for membrane ultrafi ltration, sorption and concentration of nucleic acids from aqueous media. A review

Unlike antibiotics and heavy metals, nucleic acids exist in the aquatic environment as a part of prokaryotic and eukaryotic microorganisms (bacteria, fungi, etc.) rather than in a free form. In this regard, the most important primary stage of sample preparation of an object for the quantitative analysis of DNA and RNA in natural and wastewaters includes membrane ultrafi ltration of an aqueous sample, followed by its sorption preconcentration on a solid phase carrier.
