Abstract

Objective: to treat the Isatis Indigotica fort draff to enhance its adsorption capacity for heavy metals. Methods: Isatis Indigotica fort draff was modified with NaOH, Na2CO3 and citric acid to prepare Isatis Indigotica fort draff based biosorbent; the structure was characterized by scanning electron microscopy and Fourier transform infrared spectroscopy; then the effects of solution pH value, solution concentration, adsorbent dosage, and adsorption time of copper ion solution on the adsorption performance of Isatis Indigotica fort draff based adsorbent were studied by static adsorption experiments, so as to clarify the adsorption mechanism; it provides a guide for the resource utilization of Isatis Indigotica fort draff and an experimental basis for the preparation of new adsorbents. Results: The adsorption properties of RIR-NaOH, RIR-Na2CO3, and RIR-CA were all better than RIR; the order of the maximum adsorption capacity of the modified Isatis Indigotica fort draff based adsorbent for copper ions is: RIR-Na2CO3 > RIR-NaOH > RIRCA > RIR. Conclusion: The Isatis Indigotica fort draff based adsorbent has the potential to remove heavy metals from water, and is a new type of adsorbent.
