Abstract EN
Alginate has been extensively used as absorbents due to its excellent properties.
However, the practical application of pure alginate has been restricted since the saturated adsorbent has weak physical structure and could not be regenerated easily.
In this study, a low-cost and renewable composite MnO2@alginate/Mn adsorbent has been prepared facilely for the absorptive removal of antibiotic wastewater.
FE-SEM, FTIR, and XRD analyses were used to characterize the samples.
The norfloxacin (NOR) was used as an index of antibiotics.
More specifically, the batch absorption efficiency of the adsorbents was evaluated by pH, contact time with different NOR concentration, and the temperature.
Thus, the performance of absorption kinetic dynamics and isotherm equations were estimated for the adsorptive removal process.
Parameters including ΔG0, ΔH0, and ΔS0 were utilized to describe the feasible adsorption process.
To regenerate the saturated absorptive sites of the adsorbent, the heterogeneous Fenton-like reactions were trigged by introduction of H2O2.
The results showed that the in situ regenerating has exhibited an excellent recycling stability.
The high activity and the simple fabrication of the adsorbents make them attractive for the treatment of wastewater containing refractory organic compound and also provide fundamental basis and technology for further practical application.
