Elution Evaluation of Silver Compoundcontaining Antibacterial Fabric by Atomic Absorption Spectrophotometer

User Benefits

- Analysis of silver in the eluate of antibacterial fabric is possible by atomic absorption spectrophotometer (AA). - By using both flame and furnace method, efficient measurement from high concentration to low concentration is feasible.

Introduction

With the coronavirus (COVID-19) epidemic, silver ions (Ag+) are drawing attention again. Because of their high antibacterial properties, harmlessness to humans, and long-lasting antibacterial effects, silver compounds are widely used as inorganic antibacterial agents, and many daily necessities with added silver are commercially available. Previous studies have confirmed that Ag+ has antibacterial effects against the influenza virus, common coronavirus, MRSA, etc. Herein, we introduce an example of evaluating the elution volume of silver (Ag) from an antibacterial fabric containing silver compound using the atomic absorption method. By using both the flame method, which enables rapid measurement, and the highly sensitive furnace method, it is possible to analyze eluted Ag in a wide concentration range.
