Cephalexin interaction with biosolids-derived dissolved organic matter: binding mechanism and implications for adsorption by biochar and clay

Environ. Sci.: Water Res. Technol., 2024, Advance Article
DOI: 10.1039/D3EW00590A, Paper

Peracetic Acid to Reduce Disinfection By-product Formation in Drinking Water

Environ. Sci.: Water Res. Technol., 2024, Accepted Manuscript
DOI: 10.1039/D3EW00581J, Paper
Subhajit Mondal, Erin D. Mackey, Ron Hofmann
Laboratory experiments were conducted to evaluate the ability of peracetic acid (PAA—containing 10% hydrogen peroxide by weight in equilibrium) to reduce subsequent chlorination disinfection by-product (DBP) formation (trihalomethanes, haloacetic acids,...
