The paper describes an accelerated procedure for isolating enteric viruses and a scheme for evaluating the viral contamination of pure waters, which involves the concentration of the viruses from the great water volumes by means ofa MFM 0142 membrane module with tangential filtration through an electropositive membrane (MMK) with a pore size of 0.2 microm,(More)
The authors propose a new heterogeneous photo sensitizer containing aluminum tetrakis [bis(cholinyl)phenylthio)] phthalocyanine grafted onto silica as an active phase. A poliovirus type 1 LSc2ab and RNA-containing phage MS2 model was used to show that the sensitizer had photo decontaminating activity against viruses and may be used to purify water from(More)
