Specifications

Degradation efficiency

{'zh': '100', 'en': '100'} %

Advantages

Complete degradation in one day

At 200 mg/L naphthalene, degradation efficiency reaches 100% after 1 day, with no naphthalene left on the carrier.

Stable structure

The composite gel beads show minimal changes in C 1s and O 1s peak intensities, indicating a stable three-dimensional network structure.

Applications

• Industrial wastewater treatment：Rapidly degrade high concentrations of naphthalene without secondary pollution
• Contaminated water remediation：Remove recalcitrant naphthalene from contaminated waters
• Groundwater purification：Loaded bacteria efficiently degrade naphthalene in groundwater
• Water environment monitoring：Serve as a biosensing carrier to monitor naphthalene pollution
• Biodegradable materials：The gel beads are biodegradable and environmentally friendly
