Schiff-base appended polymers for phosphate removal

The remediation of phosphate-contaminated water bodies and the effective treatment of hyperphosphatemia are two big challenges in which phosphate recognition could play a useful role. Here, we summarise briefly the state of the art in phosphate removal. Next, we present findings from synthetic and phosphate extraction studies that involve polymeric materials with pendent Schiff-base macrocycles designed to function as phosphate anion receptors.
