Hypothesis
The incorporation of humic acids into agarose hydrogels affects the transport of pharmaceuticals.
Conclusion
The addition of humic acids into agarose hydrogels decreases the diffusion coefficients of pharmaceuticals.
Supporting Evidence
- The lag time for pharmaceuticals increased when humic acids were added to the hydrogel.
- Diffusion coefficients were lower for diclofenac compared to sulphapyridine in both types of hydrogels.
- Humic acids can interact with pharmaceuticals, affecting their mobility in hydrogels.
Takeaway
This study shows that adding humic acids to a gel can slow down how quickly medicines move through it.
Methodology
The study used diffusion cells to measure how pharmaceuticals move through agarose hydrogels with and without humic acids.
Limitations
The study does not address the long-term effects of pharmaceuticals in natural systems.
