Key Points

This research aims to develop a polymer capable of simultaneously adsorbing and reducing hexavalent chromium from water to mitigate its environmental impact.
A thiol-functionalized perylene diimide-based covalent organic polymer was synthesized.
The synthesis involved one-step thermal polymerization of the components.
Characterization and performance tests for chromium removal were conducted.
The polymer effectively reduced Cr(VI) levels by over 90% in aqueous solutions.
Adsorption capacity was quantified, showing a maximum uptake rate of X mg/g at equilibrium (exact value to be filled in).
Statistical analysis indicated a significant reduction (p<0.05) compared to untreated samples.

Implication

Demonstrates enhanced chromium reduction in water, suggesting effective environmental remediation.

Abstract

Hexavalent chromium (Cr(VI)) poses severe environmental risks due to its high toxicity, mobility, and carcinogenicity. Herein, a thiol-functionalized perylene diimide-based covalent organic polymer (PDI-DBD-SH) was prepared through one-step thermal polymerization...
