Polyhydroxy-azo Porous Organic Polymers for Efficient Removal of Organic Pollutants from Water
Source abstract
Abstract
Effective adsorption and separation of organic pollutants from wastewater are essential to protecting the environment and human health. In this study, porous organic polymers (PAPOPs) containing a tri(polyhydroxy-phenyl-azo-phenyl) benzene skeleton structure were synthesized through diazotization coupling without any catalyst participation. It was found that PAPOPs have a high specific surface area, a mesoporous structure, a good thermal stability, and electronegativity. Based on these characteristics, PAPOPs demonstrated a maximum adsorption capacity of 1773.15 mg g –1 for rhodamine B (RhB), 1091.75 mg g –1 for Congo red, and 306.33 mg g –1 for tetracycline hydrochloride. Furthermore, PAPOPs also exhibited good selectivity and an extremely fast adsorption rate for RhB. The adsorption efficiency of PAPOPs did not significantly decrease even after seven repeated uses, indicating their broad application prospects in wastewater treatment.
