Table 2 The advantages of graphene oxide (GO) over traditional treatment methods for emerging contaminants
From: Graphene oxide synthesis and applications in emerging contaminant removal: a comprehensive review
Parameters for comparison | Graphene oxide (GO) | Traditional treatment methods |
|---|---|---|
Effectiveness in contaminant removal | High efficiency due to large surface area and high adsorption capacity | Variable effectiveness depending on the specific method and contaminant |
Selectivity towards target contaminants | Can be tailored for specific contaminants through functionalization | Limited selectivity, often removing a wide range of contaminants |
Adsorption capacity | High adsorption capacity, particularly for organic compounds | Varies depending on the material used; may require additional adsorbents for efficient removal |
Degradation efficiency | Can exhibit catalytic properties for degradation of certain contaminants | Dependent on the specific treatment method; may require additional steps for degradation |
Regeneration potential | Can be regenerated and reused for multiple cycles | Regeneration potential may vary depending on the treatment method |
Cost-effectiveness | Production costs are decreasing; potential for cost-effective large-scale applications | Costs can vary depending on the treatment method and scale of implementation |
Environmental impact | Potential for lower environmental impact; can be synthesized from sustainable sources | Environmental impact can vary depending on the specific treatment method and chemicals used |
