Mechanism, advantages and disadvantages of bioremediation of uranium in wastewater containing uranium
| Mechanism | Advantage | Disadvantage |
|---|---|---|
| Biosorption | There are many kinds of microorganisms available, fast adsorption rate and large capacity | The product is unstable and desorption occurs after adsorption |
| Bioreduction | Using the principle of oxidation and reduction, a relatively stable circulation system is formed and contributes to uranium enrichment, and is environmentally frienhment | The product is not stable and is prone to reoxidation under aerobic conditions |
| Biomineralization | Its product uranyl phosphate is extremely stable and can remove uranium more effectively | Requires the presence of organophosphate to react under the mediation of phosphatase |
