Heavy metal pollution has become one of the most serious environmental problems today. Due to increasing concern for environmental safety, cooperative efforts are committed to clean up contaminated water not only for food safety which is recognized as a global interest but also for human health. Conventional methods for removing metal ions from aqueous solution have been studied in detail. process are extremely expensive, especially when treating a large amount of water and wastewater containing heavy metal in low concentration, so they cannot be used at large scale. Alternative process is biosorption, which utilizes various natural materials of biological origin, including bacteria, fungi, yeast, algae, etc.
The aim was to study capacity of baker’s yeast (Saccharomyces cerevisiae) to adsorb Chromium(VI) in aqueous solution using Active dry baker’s yeast, dead baker’s yeast and Immobilized baker’s yeast.
