Preparation and Mechanism of a New Enhanced Flocculant Based on Bentonite for Drinking Water

Advances in Materials Science and Engineering, 2015
Bentonite is characterized by the large specific surface, good adsorption, ion exchange ability, and nontoxicity. An enhanced bentonite base composite flocculant (BTA) can be prepared from treating the calcium base bentonite and compositing various ...

Effects of calcium carbonate on hydro-mechanical properties of bentonite [PDF]

E3S Web of Conferences, 2020
To simulate characteristic changes of the bentonite mixing with CaCO3crystals that precipitate from groundwater around the high-level radioactive waste repositories, different amounts of CaCO3powders were mixed in the bentonite. In this study, four series of bentonite/CaCO3mixtures were prepared with different contents of CaCO3powders.

Characterizing Biopolymer Electrolytes in Zinc–Air Batteries: Challenges, Best Practices, and a Robust Workflow Guiding Future Research Paths

Advanced Energy Materials, EarlyView.
Bio‐based gel polymer electrolytes promise sustainable, mechanically adaptable zinc–air batteries, yet their progress is constrained by inconsistent characterization. This review critically links formulation, structure, interfaces, and cell performance, identifies methodological gaps under alkaline operating conditions, and proposes application ...

Synergistic Advanced Oxidation and Physicochemical Treatment Strategies for Antibiotic Removal and Resistance Mitigation in Water

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The presence of antibiotics in water not only causes environmental pollution but also increases the growth of antibiotic‐resistant bacterial genes, which pose serious threats to human beings and other water residents. Large numbers of people are reportedly affected by the resistant bacterial genes, as many broad‐spectrum antibiotics are not ...
