A separation-free and pizza-structure PAM/GCN/PAA composite hydrogel (PCH) in wastewater treatment at visible light or solar light

During wastewater treatment, the separation of powder nano-photocatalyst from treated water is a limiting factor for the commercial application of the powder photocatalysts. In this study, a photocatalyst, i.e. graphitic carbon nitride (GCN) was immobilized in network of polyacrylic acid (PAA) hydrogel to solve this issue.

The primary sources of sewage were municipal sewage and some industrial wastewater. The collected sludge was filtered with a 30-mesh screen and placed in a refrigerator at 4 ¡ãC. The analysis experiment should be completed within 1 week to eliminate the impact of related physical and chemical changes.

polyacrylamide

Polyacrylamide

Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2 -). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries. [1] Physicochemical properties [ edit]
