Abstract The rapid urbanization underscores the urgency of efficient treatment and resource utilization of municipal sludge for environmental conservation. To address this, a novel pH-responsive dual network polyvinyl alcohol/sodium alginate sludge hydrogel was devised by integrating municipal sludge with acrylic acid monomers, ammonium persulphate initiator, N, N’-methylene bisacrylamide crosslinking agent, reinforced by polyvinyl alcohol and sodium alginate through free radical cross-linking polymerization. The hydrogel’s optimal formulation was identified by adjusting the monomer, crosslinking agent, and initiator dosage while assessing its swelling behavior across various pH environments. Results revealed excellent swelling capacity, notably exhibiting a remarkable swelling More > Graphic Abstract

Abstract In this paper, the residue from bamboo factory has been used to design photo-Fenton catalyst, which has the advantages of low cost and magnetic recycling. The photo-Fenton catalytic performance of the biocarbon-based catalyst was excellent and its optimal preparation process was also explored by response surface methodology. First, bamboo-carbon fiber was selected as the photo-Fenton catalyst carrier. Subsequently, the surface of the carbon fiber was modified, with which dopamine, nano-Fe₃O₄ and nano-TiO₂ were successively loaded by hydrothermal method. After examined single factor tests, four factors including dopamine concentration, ferric chloride mass, P25 titanium dioxide mass and… More > Graphic Abstract
