Rhodamine B is a non-degradable carcinogenic dye, so it is of great significance to remove rhodamine B from wastewater. We designed and prepared a novel porous organic polymer adsorbent (DAPS-TP-POP), which contains abundant N, O, and S heteroatoms. DAPS-TP-POP was characterized through FT-IR, PXRD, TGA, TEM, BET etc. The results show that DAPS-TP-POP has high stability and abundant heteroatoms. DAPS-TP-POP has good adsorption capacity for rhodamine B. Besides, it also shows excellent recyclability.
