Hypothesis
Aminating waste newsprint paper with different agents will enhance its ability to absorb anionic dyes.
Conclusion
Amination significantly increases the dye sorption capacity of newsprint paper, with the highest capacities achieved using diethylenetriamine.
Supporting Evidence
- Amination with ethylenediamine and diethylenetriamine introduced 87% and 194% more amine groups into the sorbent's structure compared to ammonia treatment.
- The sorption capacity of newsprint paper towards RB5 increased from 7.12 mg/g to 231.5 mg/g after amination with diethylenetriamine.
- The highest sorption efficiency of the tested dyes was observed at pH 2-3.
Takeaway
This study shows that treating old newspapers with special chemicals can help them soak up more dye from water, making it cleaner.
Methodology
The study involved modifying waste newsprint paper with epichlorohydrin followed by amination with different agents, then testing the sorption efficiency of the modified papers for anionic dyes.
Limitations
The study does not address the long-term stability of the modified sorbents or the economic feasibility of large-scale production.
