Binding of aminoglycoside antibiotics to filtration materials. 1975

G H Wagman, and J V Bailey, and M J Weinstein

An investigation to study adsorption of gentamicin and other related aminoglycoside antibiotics to cellulose, diatomaceous earth (Celite), and Seitz filter sheets was carried out. Experiments with five aminoglycosides indicated that 30 to 100% of these antibiotics was adsorbed to cellulose depending on the ratio of antibiotic to adsorbent, and the total quantity could not be removed by acidification. Similarly, a study with gentamicin found adsorption to diatomaceous earth to be in the range of 33 to 98%. Neomycin and gentamicin were also readily adsorbed to Seitz filter sheets. The data indicate that large losses may occur during filtration of these antibiotics under certain conditions, and care should be taken to properly evaluate results during studies with these compounds in the presence of adsorbent materials.

D005374 Filtration A process of separating particulate matter from a fluid, such as air or a liquid, by passing the fluid carrier through a medium that will not pass the particulates. (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed) Filtrations
D000327 Adsorption The adhesion of gases, liquids, or dissolved solids onto a surface. It includes adsorptive phenomena of bacteria and viruses onto surfaces as well. ABSORPTION into the substance may follow but not necessarily. Adsorptions
