Method for removing Cr (VI) and RhB in wastewater by using pollutant modified NH2-MIL-125 (Ti)

The invention discloses a method for removing Cr (VI) and RhB in wastewater by using pollutant modified NH2-MIL-125 (Ti), and belongs to the field of wastewater treatment. According to the method, NH2-MIL-125 (Ti) is modified by adopting single Cr (VI) or RhB to obtain modified adsorbents RhB-NM and Cr (VI)-NM, then Cr (VI) in the wastewater is removed by adopting the RhB-NM, and RhB in the wastewater is removed by adopting the Cr (VI)-NM. The adsorbents RhB-NM and Cr (VI)-NM are high in photocatalytic efficiency, after the photocatalytic reaction is carried out for 120 min, the reduction efficiency of RhB-NM on Cr (VI) is 99.1%, and the degradation efficiency of Cr (VI)-NM on RhB is 100%; compared with the NH2-MIL-125 for removing Cr (VI) and RhB, the NH2-MIL-125 has the advantage that the removal efficiency is obviously improved. 本发明公开了利用污染物改性NH2-MIL-125(Ti)去除废水中Cr(VI)和RhB的方法，属于废水处理领域。本发明采用单一的Cr(VI)或RhB对于NH2-MIL-125(Ti)进行改性，得到改性吸附剂RhB-NM和Cr(VI)-NM，之后采用RhB-NM去除废水中的Cr(VI)，采用Cr(VI)-NM去除废水中的RhB。本发明采用的吸附剂RhB-NM和
